Assembly (continued)
Mounting the Lifting Frame into position.
1.
Position the Stop Bar (3) and Lifting Frame (2) as shown in the Assembly Drawing, so
that the holes on the arms of both the Stop Bar (3) and Lifting Frame (2) line up with
the holes on the welded tabs on the Rear Lift Arms (4). Place Pins (28) through the
Lifting Frame (2), theTabs, Bushings (32), and Stop Bar (3).
Please note:The Bushings fit around the Bolts and inside the Stop Bar.
2.
Secure the Bolts with Washers (29 and 30) and Spring Pin (38).
Installing the Pedal, Spring, and Handle.
1.
Loosen and remove the screw that holds in the Foot Pedal (24). Insert the Foot Pedal
(24) into the receiver of the Jack (36). Use the screw you loosened from the pedal
assembly to secure the Foot Pedal (24) into the receiver of the Jack.
2.
Insert the Handle (1) into the receptacle on the Lifting Frame (2) and secure it with the
Bolt (27).
Testing the Stop Bar (33 and 35).
The Stop Bar (33 and 35) must be locked in one of the four positions after lifting a load.
Not engaging the Stop Bar (33 and 35) may result in serious injury or death, and damage the
Lift. Before each use, check that the lower tips of the Stop Bar (33 and 35) fit behind the
notches on the both sides of the Frame Base (11). See FIGURE 2.

Operation
Warning!! Never work on a vehicle that is on the ATV Motorcycle Jack, or leave it unat-
tended, if the Stop Bar (33 and 35) is not in place, or the Lock Bolts (37) are not engaged
(lifting the casters off of the ground).
Note: Keep fingers and hands away from the Lift Arms (4 and 6) when raising or lowering the
Lift. Keep onlookers and children a safe distance from the Lift during operation.
Raising the Lift.
Note: Use a second person to assist, if needed.
1. Use the Handle (1) to roll this product and position it next to the load you wish to lift. To
lower the lift so it will fit under the load, gently depress the Release Pedal (26).
Note: Check the load manual for recommended lifting points.
2. Once positioned under the load at the correct lifting points, turn the Lock Bolts (37) until
they contact the ground and lift the Swivel Casters (20) slightly off of the ground, to keep the
lift from rolling.
3. Use tie-down straps (not included) to secure the load. Repeatedly depress the Foot
Pedal (24) slowly, to raise the Saddle Platform (5).When the lift makes contact with the load,
make sure the load sits evenly on the two Saddle Platform (5) before raising the load off of the
ground. If the load is not evenly distributed on the Saddle Platform (5) and it not secured in
place with tie-down straps, it may fall from the Saddle Platform (5), resulting in possible per-
sonal injury and property damage.
4. Continue to raise the lift until you reach the desired height. Disengage the Stop Bar (3) from
the spring. You must lock the lift at one of the four locking positions with the Stop Bar (3). See
FIGURE 2.
5. This is a lifting device only. It is not designed to support loads for extended periods of
time. Do not work directly under the ATV lift.
Lowering the ATV Motorcycle Jack.
Note: Remove all tools from under the lift before lowering.
1. Depress the Foot Pedal (24) slowly to raise the lift enough to disengage the Stop Bar (3).
Lift it up and attach it to the spring.
2. Make sure everyone is clear and slowly depress the Release Pedal (26) to lower the lift.
NOTE:The Rear Pedal is designed with a Safety Valve, so it needs to be pressed down
only part way to lower the load. Once the load is on the ground, remove the tie-down straps
(not included). When the lift is clear of the load, turn the Lock Bolts (37) until they are clear of
the ground, allowing the Swivel Casters (20) to firmly contact the ground. Roll the ATV Motor-
cycle Jack clear of the load.
Maintenance
1. Keep your ATV Motorcycle Jack dry, protecting it from wet, corrosive environments.
2. Periodically lubricate the Jack’s moving parts.
3. Periodically check that all of the Jack’s hardware is securely fastened.
If the Jack does not work to full capacity, you may have air in the hydraulic system.

Maintenance (continued)
Bleeding and filling the Jack with hydraulic oil.
1. Place the Lift on a flat, level, solid surface.
2. If just filling the Jack, open the Oil Filler Plug (10a) and check the oil. Fill to the top of the
Oil Reservoir (9a) with a high quality hydraulic oil if necessary.
3. If bleeding, with the Oil Filler Plug (10a) removed, use one foot to step on and keep the
Release Pedal (26) down, while you quickly pump the Foot Pedal (24) ten times. This will
bring all the air out of the system. Continue pumping until no more air bubbles appear. Fill to the
top of the Oil Reservoir (9a) with a high quality hydraulic oil if necessary. Repeat if necessary.
4. Replace the Oil Filler Plug (10a) .
5. Test the Jack. Make sure it is functioning properly before attempting to lift another load.
Pump the Foot Pedal (24) up and down several times, and test the Release Pedal (26) to
make sure it is working properly; if not, repeat the above process. If the lift continues to func-
tion improperly, have a qualified service technician check the product.
