Assembly
Bleeding the Hydraulic Jack
This item will be mostly assembled out of the box.
1. Pull out the lift and place it on solid at ground. Insert the bottom axle (18) into the lift as the dia-
gram shows (may already installed). Add the two casters (19) on both sides of the axle and lock in
place with washers (27) and R-pins (7).
2. Install the cradles (3) into the top frame (2) on both sides. Adjust the position (width) of both cradles
and lock the position with the lock pins (1). Make sure the cradles t under the mower’s wheels
perfectly. DO NOT allow the wheel to sit outside the cradle edge; it may cause the mower to fall
during lifting and cause damage and personal injury.
IMPORTANT! Before rst use, check for proper hydraulic uid level in the hydraulic jack (25).
Then thoroughly test the lift for proper operation prior to its actual use. If the lift appears not
to be working properly, it may be necessary to bleed its hydraulic system of excess air.
1. Remove the uid ll plug on the side of the bottle jack.
2. With weight on the lift, turn the pump handle (4) counterclockwise to release the valve.
3. While holding the weight and pump in the released position, quickly pump the handle (4) up and
down several times to purge air from the system.
4. Check the uid ll hole and, if necessary, top o󰀨 the jack’s uid reservoir with high grade hydraulic
uid (sold separately).
5. Replace the uid ll plug.
6. Test the lift several times for proper operation before attempting to lift a load.
If, after purging, the lift still does not appear to be working properly, do not use the lift until it
has been repaired by a qualied service technician.
Adding Hydraulic Fluid
1. Remove the uid ll plug on the side of the bottle jack.
2. Add high grade hydraulic uid (sold separately) into the uid ll hole slowly until the uid just begins
to run out of the hole.
3. Replace the uid ll plug.

Lifting
Lowering
1. Pull out (unlock) the brake puller (13) of the safety device
on both sides of the lift.
2. Lower the lift by releasing the wing nut on the jack with
the notched end of the handle (4); put some weight on
the cradles if needed. Once lowered, tighten the wing nut
again.
3. Align the mower’s front wheels with both cradles. Slow-
ly move the mower on to the cradles. Once positioned
under the load, push back the brake puller (13) on both
sides of the lift. (You may need to chock the wheels on
the back side of the casters to keep the lift sturdy while
riding on the mower).
4. Use tie-down straps (sold separately) to secure the load.
Fit the curved end of the handle (4) into the handle tube
on the jack. Pump the handle (4) slowly to raise the lift.
When the lift makes contact with the load, make sure the
load sits evenly on the cradles (3) before raising the load.
If the load is not evenly distributed on the two cradles
(3) or not secured in place with tie-down straps, it may
fall from the lift, resulting in personal injury and property
damage.
5. Continue to raise the lift to the desired height. Lock the lift
at one of the three locking positions on the brake puller
(13). Not engaging the brake puller (13) may result in
serious injury or death, and damage the lift. (See mower
owner’s manual for recommended lifting points.)
1. Carefully remove all tools, parts, etc. from under the lift.
2. Fit the curved end of the handle (4) into the handle tube
on the jack. Pump the handle (4) slowly to raise the lift
enough to disengage the brake puller (13).
3. Slowly release the wing nut on the jack with the notched
end of the handle (4) to slowly and gently to lower the
load. Never allow the load to come down quickly or sud-
denly.
4. Once the load is on the ground, remove the tie-down
straps.
5. Clean external surfaces of the lift with a clean, dry cloth.
Store lift in a dry, indoor area out of the reach of children.
