If extension cords are used, they must meet or exceed the following specifications: a. Heavy duty (15 amps). b. Must be grounded. c. Must be taped to the floor to avoid a trip hazard. If your trainer is placed in a permanent position, for safety purposes run the wiring in from overhead if possible. This will prevent unnecessary trip hazards associated with laying extension cords on the floor. CAUTION The trainer is shipped without hydraulic oil. DO NOT start the steering pump or hydrostatic pump until it has been filled with the recommended oil. Running a hydraulic pump without oil will result in severe and irreparable damage. WARNING DO NOT PUT YOUR HANDS NEAR A LEAK OR ATTEMPT TO SEARCH FOR A LEAK WITH YOUR HANDS. • Hydraulic oil can inflict three types of injuries: - skin penetration, burn, and eye. • Hydraulic oil can penetrate skin at pressures as low as 100 PSI (6.9 bar). Skin penetration can result in severe injury, permanent loss of hand or finger motion, hand or finger amputation, or death. • If you get injected, see a physician immediately. Do not eat or drink. • Take the MSDS sheet of the injected material with you. If the physician wants to simply clean and bandage the wound, refer him/her to http://www.fluidpowersafety.com. • Hydraulic oil can inflict second and third degree burns at normal operating temperature - as low as 130ºF (54.4ºC). 1-2 1.0 SAFETY FIRST! - Safety Instructions Operating or observing the operation of this trainer without safety glasses may lead to an accident which could result in severe eye injury or blindness. This trainer is to be operated only under the supervision of a trained, authorized instructor. Follow all safety instructions in the operator handbook before using this trainer. WARNING Prevention is better than cure! An eye-wash station must be located in an accessible location that requires no more than ten (10) seconds to reach and should be located within a travel distance no greater than 100 feet (30.5 m) from the hazard (ANSI Z358.1-1998). WARNING WARNING Post a warning sign on the entry door into the hydraulic training center. Warn people who enter the room that hydraulic system(s) are in operation and that they must wear safety glasses with side- shields which conform to ANSI Z87.1. WARNING Wipe all excess oil from trainer during operation and trainer activi- ties. Failure to maintain a clean, oil-free working environment could lead to a slip hazard injury. 1-3 1.0 SAFETY FIRST! - Safety Instructions WARNING The trainers have been designed to operate safely. Any type of change or modification could have a detrimental effect on that safety. Accordingly, ALL modifications or changes, regardless of how minor, must be approved in writing, by the FPTI™ - these include: • Changes in the design of the trainer. • Adding component(s) to the trainer. • Removing component(s) from the trainer. • Failing to properly maintain the trainer. • Making component substitutions. • Using the trainer for any purpose other than training and education. 2.0 Unpacking Your Trainer - SAFETY INSTRUCTIONS: a.

The distance from the allen-screw on the motor-shaft and the proximity switch sensor is critical for proper operation. The factory set distance is approximately 0.080” (2mm). Figure 5-1 5.0 Familiarizing yourself with the MF300VCLS Trainer - Hydrostatic (closed-loop) System Figure 5-2 5-1 When the distance setting is correct, the red “sensor” light on the tachometer display will flash when the motor shaft is rotating. If the tachometer fails to display motor shaft speed, and the red light is not flashing, the problem is usually attributed to the “gap” setting. If the light does not flash when you move the sensor away from, or toward, the motor shaft, refer to troubleshooting information (Section 11.0), for further information. 5.2 Charge Pressure Gauge (0-100 PSI/0-6.9 bar) - Hydrostatic transmission control panel (Figure 5-3) The normal charge pressure is 20-25 PSI (1.38-1.72 bar). Figure 5-3 5-2 5.0 Familiarizing yourself with the MF300VCLS Trainer - Hydrostatic (closed-loop) System 5.3 Flow meters - Hydrostatic transmission (Figure 5-4) Each “leg” of the closed-loop circuit has a 0-5.0 GPM bi-directional flow meter. The flow meters read flow in two directions. Figure 5-4 5.0 Familiarizing yourself with the MF300VCLS Trainer - Hydrostatic (closed-loop) System 5-3 5.5 Hydrostatic Pump - (Figure 5-6) Figure 5-6 5.4 Wheel-Drive Motors - (Figure 5-5) Each rear wheel is equipped with a 0.5 cu.in./rev. hydraulic motor. The motors can be connected in parallel or series depending on the activity a student is undertaking. The physical size of a hydraulic motor can be very misleading with respect to a motors torque output. Small motors can produce relatively high torque. For safety purposes, the wheels on the MF300VCLS trainer rotate indepen- dently of the motor drive shaft. The wheel will spin when the motor rotates. However, the wheels will stop rotating if any attempt is made to prevent the motor from rotating or stop the wheels while in motion. Figure 5-5 Displacement: 0.37 cu.in./rev. (6.1 cc/rev.)

Figure 7-4 8-1 8.0 Familiarizing yourself with Components used with the MF300VCLS-TS (troubleshooting) Trainer - 8.1 Pressure/Leak Test Pump - The pressure/leak test pump is designed for testing a variety of hydraulic components. While it bears the resemblance of a commercial porta-power, it is not a porta-power. The pressure/leak test pump does not need to be filled with oil. It automatically fills whenever the steering power unit is operating. If, while using the pressure/leak test pump it runs out of oil, simply run the pump run for approximately 30 seconds, and it will re-fill. To operate the pressure/leak test pump, rotate the knob (Figure 8-1) clockwise until it stops, and operate the hand-lever. To release the pressure, rotate the knob counterclockwise until it stops. Figure 8-1 Figure 8-2 Steering 8.2 “Fault-Set” Toggle-switches - The row of 2-position toggle switches located across the top of the control panels cause various components to “wear out.” This unique feature creates “real world” faults for students to find. Steering System - There are ten (10) two-position toggle switches for setting faults in the steering system. They are located across the back of the steering control panel (Figure 8-2). The switches ON/OFF positions are purposely staggered. Reference numbers (1 to 10) are located directly above each switch. 8-2 8.3 “Fault-Set” Toggle-switch Master Switch - The trainer is designed for teaching hydraulic system and hydraulic system/ component diagnostics. To avoid inadvertent operation of the “fault-set” toggle switches, the toggle switch circuit is equipped with a master switch (Figure 8-4). The master switch can be locked in the ON or OFF position. Figure 8-4 8.0 Familiarizing yourself with Components used with the MF300VCLS-TS (troubleshooting) Trainer - cont’d. Figure 8-3 Hydrostatic Hydrostatic System - There are five (5) two-position toggle switches for setting faults in the hydrostatic transmission system. They are located across the back of the hydrostatic transmission system control panel (Figure 8-3). The switches ON/OFF positions are purposely staggered. Reference numbers (1 to 5) are located directly above each switch. Step 2: Next, carefully aim the laser between the openings in the fan safety guard at the reflective tape (Figure 8-7). Hold the tachometer steady, and depress the white button. Wait a few seconds for the tachometer to respond. Pushing the black button on the tachometer will automatically submit the indicated speed to the tach- ometer’s memory. To learn more about the tachometer, read the instruction manual (See section 17.0). 8-3 Figure 8-7 8.0 Familiarizing yourself with Components used with the MF300VCLS-TS (troubleshooting) Trainer - cont’d. 8.4 Digital, Hand-Held, Laser-Type Tachometer (optional - Part # HC-DT207L) - The hand-held tachometer is used primarily when students are learning diagnostic skills. Its main purpose is for students to observe and record prime-mover (electric motor) speed. The state-of-the-art tachometer needs a reflective feedback medium to operate properly. A piece of self-adhesive reflective tape has been attached to the electric motor’s cooling fan (Figure 8-5) for this purpose. Step 1: To operate the tachometer, first rotate the dial to the correct position - “non-contact RPM” (Figure 8-6).

Place the fourteen (14) hoses in the back four rows. The “T’s” can be placed in the front row of the caddy for convenience and accessability (Figure 10-1). Figure 10-1 10.2 Fill the Oil Reservoir - Oil type/grade: AW-32 hydraulic fluid. Reservoir Capacity: Approximately 4.0 U.S. gallons (15.14 liters). Step 1: Remove the filler/breather cap (Figure 10-2). Place a funnel in the filler neck. Hand-tighten only. Figure 10-2 10.0 Preparing Your Trainer for Use - cont’d. 10-2 Figure 10-3 Figure 10-4 Step 2: Add oil until it reaches the “OIL LEVEL” mark on the reservoir (Figure 10-3). Step 3: Connect the trainer to a 115 volt, single-phas electrical outlet (minimum 20 amps) using an approved electrical cord with ground. If the cord lays on the ground, it must be properly taped to prevent a trip hazard. All wiring must be done by a certified electrician. Step 4: Remove a hose from the hose caddy and use it to bridge the closed-loop. (Figure 10-5). Step 5: Start the power unit. Figure 10-5 Step 6: Observe the charge pressure gauge. The pressure must reach 45-75 PSI (3.1-5.2 bar) within approximately 15 seconds after starting the motor. Step 7: Re-check the oil level. Add oil if necessay. Step 8: Remove the funnel. Step 9: Replace the oil filler/breather cap and tighten by hand. Step 10: Remove the hose and store it in the hose caddy. 10.0 Preparing Your Trainer for Use - cont’d. 10-3 11.0 Safety Features - 11.1 Quick-connect/disconnect Safety Covers (if applicable) - The male quick-connect/disconnects (non flat-face connector style) are fitted with spring-loaded, self-closing, safety covers. The safety covers will diffuse the oil in the unlikely event that a quick-connect/disconnect remains open. To attach a hose to a quick-connect/disconnect, pull the cover away from the connector until the connector is exposed (Figure 11-1). Figure 11-1 Figure 11-2 Figure 11-3 Figure 11-4 Figure 11-5 11-1 Make sure that the hose-end connector is properly engaged in the male connector. If the connection is incomplete it will not allow oil to pass (Figures 11-4 & 11-5). NOTE: Check to see if the connector is secure by pulling on the connector. NOTE: Do not move the safety covers more than what is necessary to make a connection. Excessive force could cause the spring-loaded cover to distort. WARNING: Damaged safety covers must be replaced immediately! Push the female connector onto the male connector and push it until it stops (Figures 11-2 & 11-3).

Check red Power ON warning light. If not illuminated check power supply. b. If red Power ON warning light is illuminated, reset breaker on motor starter. To reset breaker, set switch to OFF position and push down firmly on the switch. Attempt to start motor. If motor fails to start, the electrical circuit must be checked by a certified electrician. a. Pump noise is usually caused by cavi- tation. Check oil level - add if necessary. a. Check pump flow - Flow adjustment screw must be set for 1.0 GPM (3.79 Lpm) flow rate. Check steering system safety relief valve pressure - Set at 1000 PSI (69 bar). 14.0 Troubleshooting your Trainer - cont’d. 14.1 Digital Tachometer - (panel-mounted) - The distance from the motor-shaft key-way and the proximity switch is critical for proper operation. The factory set distance is 0.08” (2 mm). If the tachometer fails to display motor shaft speed, and the red light is not flashing, the problem is usually attributed to the distance setting or the “gap”. Here is a simple technique for setting the “gap”: 1. Slightly loosen the upper and lower securing nuts on the sensor shaft. 2. While observing the red light on the tachometer, slowly move the sensor assembly away from the shaft, increasing the “gap.” If the light starts flashing, the tachometer will begin to operate - the gap was too small. 3. Tighten the two securing nuts and re-check the tachometer display. 4. If the light fails to start flashing, slowly move the sensor toward the motor shaft until the light starts flashing. Adjust it until you feel the sensor barely contact with the key in the motor shaft - DO NOT force it against the key! 5. Tighten the two securing nuts and re-check the tachometer display. If the light does not flash when you move the sensor away from, or toward, the motor shaft, refer to the troubleshooting section of this components documentation which can be found in section 17.0 - Manufacturer’s Service/Operation Literature, for further information. NOTE: When adjusting the sensor, turn the motor shaft to ensure the sensor does not interfere with the shaft. 14-2 15-1 15.0 Where to Get Help - If, after following the troubleshooting guide the problem(s) you are experiencing still persist, call the Fluid Power Training Institute™ for assistance at 1-888-222-3421.
