- Never work under a raised mower without engaging all safety locking mechanisms.
- Keep hands and feet clear of moving parts during lifting and lowering.

3. Assembly Instructions
The Guardian Zero Turn Lawn Mower Lift Jack requires some assembly. While the product is designed for straightforward setup, careful attention to detail is necessary. Refer to the diagrams and ensure all components are correctly installed.
3.1 Package Contents
Before beginning assembly, verify that all parts are present. If any parts are missing or damaged, contact customer support.
- Main Lift Frame with Hydraulic Pump
- Handle Assembly
- Wheel Cradles (2)
- Adjustable Extension Arms (2)
- Connecting Rods/Pins and Cotter Pins
- Wheels (4) and Axles
- Hardware (bolts, nuts, washers)
3.2 Assembly Steps
- Attach Wheels: Secure the four wheels to the main lift frame using the provided axles and hardware. Ensure wheels spin freely.
- Install Handle: Insert the handle assembly into the designated slot on the main frame and secure it with the appropriate pin or bolt.
- Connect Extension Arms: Attach the adjustable extension arms to the main frame. These arms allow for width adjustment to accommodate different mower sizes.
- Mount Wheel Cradles: Slide the wheel cradles onto the extension arms. These cradles are designed to hold the mower's front wheels. Secure them with pins.
- Hydraulic Pump Connection: Ensure the hydraulic pump mechanism is securely connected to the lifting arm of the main frame. This connection typically involves a pin and circlips. (Note: Some users have reported difficulty with circlip installation in tight spaces. An angled circlip tool may be helpful.)
- Final Check: Before first use, inspect all connections, bolts, and pins to ensure they are tight and properly secured.

4. Operating Instructions
Follow these steps to safely lift and lower your zero-turn or riding lawn mower.
4.1 Preparing the Mower and Lift
- Park the mower on a flat, stable surface. Engage the parking brake and turn off the engine.
- Adjust the width of the lift's wheel cradles to match the width of your mower's front wheels. The cradles accommodate wheels up to 9-7/8 inches wide and an outside wheel base up to 50.5 inches. Secure the cradles with the provided pins.
- Position the lift jack directly in front of the mower, aligning the wheel cradles with the mower's front wheels.

4.2 Lifting the Mower
- Carefully drive the mower onto the lift's wheel cradles until the front wheels are fully seated.
- Ensure the mower is centered and stable on the cradles.
- Using the foot-operated hydraulic pump pedal, slowly pump to raise the mower. The lift has three locking height positions: 16 inches, 21.25 inches, and 27 inches.
- As the lift raises, ensure the automatic locking bolts engage fully into the desired height position. Listen for a distinct "clack" sound. Always verify both locking bolts are engaged before working under the mower.

4.3 Lowering the Mower
- Before lowering, ensure no tools or body parts are under the mower.
- To lower the mower, press the separate foot pedal designed for controlled lowering. This will disengage the locking mechanism and allow the hydraulic system to slowly release the lift.
- Guide the mower off the cradles once it is fully lowered to the ground.

5. Maintenance
Regular maintenance ensures the longevity and safe operation of your lift jack.
- Cleaning: Keep the lift clean and free of dirt, debris, and moisture.
- Lubrication: Periodically lubricate all pivot points and moving parts with a suitable grease or oil. Pay attention to the hydraulic cylinder rod; when stored, wrap an oil-soaked rag around the exposed section to prevent corrosion.
- Inspection: Before each use, inspect the lift for any signs of damage, wear, or loose hardware. Check the hydraulic system for leaks.
- Storage: When not in use, store the lift in a dry, protected area. The cradle components can be removed for compact storage.
6. Troubleshooting
If you encounter issues with your lift jack, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lift does not raise or raises slowly. | Low hydraulic fluid, air in the system, or overloaded. | Check hydraulic fluid level and refill if necessary. Bleed air from the system (refer to hydraulic pump manual if available). Ensure load does not exceed 550 lbs. |
| Lift lowers unexpectedly. | Release valve not fully closed, hydraulic leak, or faulty locking mechanism. | Ensure the lowering pedal is not engaged. Inspect for hydraulic fluid leaks. Verify locking bolts engage correctly. Do not use if locking mechanism is faulty. |
| Mower is unstable on the lift. | Mower not centered, cradles not adjusted correctly, or uneven surface. | Reposition the mower to be centered. Adjust cradle width to fit snugly. Move the lift to a flat, stable surface. |
| Difficulty with assembly. | Unclear instructions, missing hardware, or tight tolerances. | Review assembly steps carefully. Contact customer support for missing parts. For circlips, an angled tool may assist. |
