MOJACK 550 MOWER LIFT (01) PDF Document

READ AND FOLLOW ALL SAFETY RULES AND INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING TO OPERATE THIS MACHINE. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.

• Read and understand all safety and operating instructions before using the mower lift.

• Never allow anyone unfamiliar with the safety or operating instructions to use the lift.

• Follow all safety and servicing instructions provided by the lawn mower’s manufacturer before using the lift.

• Do not modify the lift in any way. Any modifications will void any and all warranties and could compromise your personal safety.

• When using the lift, keep ALL bystanders at a safe distance away from the mower lift.

• The lift must be used on a solid level surface.

• Only lift the FRONT end of the mower.

• Do not lift the front end and back end of the mower at the same time.

• Do not exceed the lifting capacity of 550 lbs. (249 kg) front end weight.

• Only use the lift for mowers that properly fits in the provided wheel pads. (ie. 10″ to 17″ diameter and within the inside to outside wheel measurements of 18.5″ to 47.5″).

• Both Left and Right Wheel pads must be equal distance from the T-bar to maintain proper balance.

• Always stop engine and remove key before beginning any work on the mower.

• Always place wheel chocks (not included) behind the back tires of the mower before beginning maintenance. For additional safety, you may apply the parking brake after the wheel chocks are in place.

• Never operate the engine while using the mower lift.

• Do not remove safety warnings or decals from lift.

• Please make sure that the space below the mower is big enough to work safely under the mower.

• Please make sure that the mower is stable enough for work.

• Failure to follow these warnings may result in property damage and serious bodily injury or death.

IMPORTANT: The mower lift is intended for use with mowers only. Do not exceed 550 lbs. (249 kg) front end weight. It should never be used to service other types of machinery.

Step 1: Unpack and Inventory

Remove the lift from the package. Inventory items to be certain all parts and hardware are present. Identify the Right and Left Wheel Pads. IMPORTANT: The Wheel Pads are side specific.

Step 2: Install Wheel Pads

Slide the wheel pads into the T-Bar. Line up the wheel pads to the front tires of the mower. The multiple holes allow for adequate adjustment to fit the front tires of the mowers. NOTE: Inside to outside wheel pad expansion is 18.5″ – 47.5″. Secure the wheel pads to the T-Bar with the Push Pins. Make sure the Push Pins are securely inserted into the holes. NOTE: Wheel pads must be equal distance from the T-Bar to maintain proper balance.

Step 3: Attach Safety Straps

Attach the Safety Straps to the wheel pads. Insert the strap loop through the wheel pad around the smaller wheel pad tube. Thread strap hook and buckle through the strap loop and pull until tight. Repeat with the other Safety Strap and wheel pad.

Step 4: Reverse Front Tires of ZTR Mower (optional – if not applicable, skip to Step 5)

In some cases, the mower deck or anti-scalping wheels will hit the Lift Arm while the mower is being raised. This is often the case if part of the deck (including the anti-scalping wheels) protrudes past the center line of the front wheels of the mower. If this happens:

• Rotate the front tires 180° so that they are in the reverse position.

• Slide the lift as close to the wheels as possible.

Step 5: Move the mower onto the Wheel Pads

Wheel Pads must be properly aligned with the mower’s front tires (see Step 2) and secured with Push Pins. NOTE: Wheel pads will accommodate 10″-17″ tire sizes. The Jack MUST be on a hard solid level surface. NOTE: If the lift slides when moving the mower onto the Wheel Pads, place Wheel Chocks behind the lift’s wheels to prevent it from sliding.

Step 6: Secure the front mower tires to the Wheel Pads using the Safety Straps.

Extend the Safety Strap over the top of tire or over the top of mower wheel arm and secure the hook into the loop on the wheel pad. Squeeze the metal buckle and pull end of strap to tighten the Safety Straps over the top of the tires to secure mower to Wheel Pads. NOTE: Wheel Pads accommodate wheel sizes from 10″ – 17″ (25cm – 43cm). NOTE: Inspect Safety Strap for wear before each use.

Step 7: Operating the hydraulic cylinder.

To raise the lift: Close the release valve. Turn Release Valve clockwise to CLOSE. Rotate clockwise until the Release Valve stops turning without effort. DO NOT over tighten the Release Valve.

Step 8: To raise the mower.

Make sure the cylinder valve is closed by turning the valve clockwise. If yes, proceed to insert the handle into the cylinder handle opening. Proceed to pump the handle up and down to raise the lift to the desired height. The cylinder will use pumping action of the handle to raise the lift. The automatic locking mechanism will engage at three different lift heights. The 3 locking positions are: 18″, 21″, 26″. As you pump the handle to raise the lift you will hear a click sound at each of the locking positions indicating the locking bar is fully secured. NOTE: Make sure your mower is in neutral before you raise your mower. The mower wheels need to move freely as the mower raises.

The automatic locking mechanism will engage at three different lift heights: 18″, 21″, and 26″. As you pump the handle to raise the lift, you will hear a click sound at each locking position, indicating the locking bar is fully secured.

• LOCKED: When the Locking Bar Cover is parallel with the Locking Bar, the Locking Pin is LOCKED in the Bar teeth.

• NOT LOCKED: When the Locking Bar Cover is raised or angled with the Locking Bar, the Locking Pin is NOT LOCKED in the Bar teeth.

The automatic locking mechanism must be engaged in one of the three lock position notches on the Locking Bar before proceeding to service the mower.

Step 9: Preparing the mower for service.

Before servicing, place wheel chocks (not included) behind the back tires of the mower and apply the parking brake on the mower. YOU MAY NOW SERVICE THE MOWER.

Step 10: To lower the mower.

1) Before Lowering the Lift, Remove the Wheel Chocks and Parking Brake.

2) IMPORTANT WHEN LOWERING: YOU MUST USE THE HANDLE TO OPERATE THE CYLINDER. Pump the handle twice to release pressure from the locking position.

3) Step down on the Locking Bar with your foot, at the same time, slowly turn the cylinder release valve with the handle counterclockwise. Only 1/2 turn is required to release the pressure. Do not overturn the release valve. Keep your foot on the Locking Bar until it is completely lowered or passed the last locking position.

To open the release valve to lower the lift, turn the Release Valve counterclockwise to OPEN. WARNING! Only requires 1/2 a turn before pressure begins to release. DO NOT overturn the Release Valve or the valve screw will come out and spill hydraulic fluid.

Important: Use only a good grade hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the potential for sudden and immediate loss of load.

HOW TO REPLACE THE HYDRAULIC CYLINDER

1) To remove the cylinder, remove the bolts holding the cylinder in place.

2) Remove old cylinder and install new cylinder using the same hardware.

ADDING OIL TO HYDRAULIC CYLINDER

1) With saddle fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove oil filler plug.

2) Fill until oil is level with the filler plug hole, reinstall oil filler plug.

CHANGING OIL IN HYDRAULIC CYLINDER

For best performance and longest life, replace the complete fluid supply at least once per year.

1) With saddle fully lowered and pump piston fully depressed, remove the oil filler plug.

2) Lay the jack on its side and drain the fluid into a suitable container. NOTE: Dispose of hydraulic fluid in accordance with local regulations.

3) Fill with good quality jack oil. Reinstall oil filler plug. We recommend Mobil DTE 13 or equivalent.

LUBRICATION

1) A coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that wheels, casters and pump assemblies move freely.

2) Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with a clean, oil soaked rag. NOTE: Never use sandpaper or abrasive material on these surfaces.

STORAGE

When not in use, store the Bottle Jack with pump piston and ram fully retracted.
