INSTALLATION INSTRUCTIONS
You will need common hand tools that most homeowners have, like a hammer,
screwdrivers and pliers, but in addition, you may need some tools that are not common.
Each installation is somewhat different and depends on how much room you have to
work around the lift.
Required Tools
1. Fork Lift
2. Metal Shears
3. Socket Wrenches with Ratchet
4. Adjustable Wrench
5. Pliers
6. Flat Blade Screwdriver
7. Gloves
Unloading Lift
You’ll need a forklift that can handle about 2,000 to 2,300 pounds and operate on a
smooth surface.
Un-banding Lift
The steel bands which secure the lift parts to the pallets are heavy duty. You’ll need a
pair of metal shears or tin snips to cut the steel bands. Be very careful when doing this
because the bands will tend to fly apart when they are cut, and the heavy lift parts may
shift when freed from the steel bands. Stand to the side of the steel bands when cutting
them, while using gloves when removing the cut bands because they have sharp edges.
You can move the large piece to the garage with the forklift. Other smaller pieces can be
moved manually.
STEP 1: Assemble Dolly & Lock Release Hand Lever
A. Remove dolly components from the carton and assemble together (Fig. 1).
B. Mount the Lock Release Hand Lever to the dolly ‘side’ handle (Fig. 2).

OPERATION INSTRUCTIONS
Never operate the Lift if the Safety Lock Assembly is not working properly.
1. Plug the Power Cord of the Lift into a properly grounded, 3-hole, electrical receptacle or extension cord.
2. Squeeze and release the Lock Release Hand Lever several times and while doing so, observe that the
Safety Lock Assembly operates properly in response to the Hand Lever. Release pressure on the Hand
Lever to release Lock.
3. Press and hold the Power Unit Switch and observe that the Safety Lock Assembly "clicks” into place as
the Lift rises.
There are safety ‘catches’ on the Safety Lock Assembly as the Lift rises. Once the Safety
Lock Assembly locks into each of the safety catches, you must squeeze and hold the
Hand Lever to release the lock to lower the Lift.
4. Once the Lift is fully elevated, release pressure on the Power Unit Switch.
5. Without squeezing the Hand Lever, press down on the Power Unit Pressure Relief Valve Handle and
hold. Observe that the Lift will slightly lower to engage the next lowest Lock position.
If the Safety Lock Assembly does not properly engage the lock position, fully lower the
Lift and have a qualified service technician immediately repair the Safety Lock Assembly.
6. Should the Safety Lock Assembly not operate as described in step #5, raise the Lift slightly to take
pressure off the safety catches. Then, while squeezing the Hand Lever lower the Lift fully to the floor.
When working properly, you must BOTH squeeze in and hold the Lock Release Hand
Lever and press in and hold the Pressure Relief Valve Handle to lower the Lift.
Vehicle Positioning, Lifting & Lowering
1. Before driving a vehicle onto the Lift make sure that the Lift is fully lowered and position the Arms and
Pads are positioned inward.
2. Carefully drive vehicle over the Lift while keeping the vehicle parallel with the Lift, along with aligning
the (COG) center of gravity of the vehicle with the center of the Lift.
The “Center Of Gravity” (COG) of the vehicle is the balance point at which there is equal
vehicle weight placement for both ‘front to back’ and ‘side to side’. The COG is not
necessarily the dimensional center of the vehicle, but is often slightly towards the engine
from the dimensional center of the vehicle.
3. Turn off vehicle's engine and engage the parking brake.
4. Read the vehicle owner's manual to identify the recommended vehicle lifting points.

11
MR6K-48X
Dec 2017
5. Position the Arms outward and position the Saddle Pads to contact the vehicle lifting points.
6. Do not lift the vehicle if you cannot establish secure and level lifting points. Do not use sub-standard
shims or other devices in place of approved and recommended Saddle Pad Adapters. Never use the
Lift without the Saddle Pads in place for each Arm.
7. Once the Saddle Pads have been positioned under the vehicle lifting points, push the Power Unit
Switch to lift the vehicle slightly, and test to make sure the vehicle is well balanced and the contact
between the Saddle Pads and vehicle’s lifting points are secure. Then, proceed to lift the vehicle to the
desired height.
8. When the vehicle has been lifted to the desired height, and the Safety Lock Assembly has locked in
place, make sure to install proper safety jack stands (not included), under the vehicle once it is lifted to
the desired height, as an additional safety measure.
9. Once the repair work to the vehicle is completed make sure to remove all tools, safety jack stands, and
materials form under the vehicle and Lift. Also, make sure the work area is clear and it is safe to lower
the vehicle.
10. To lower the Lift, use the Power Unit Switch to slightly raise the vehicle to remove pressure off the
Safety Lock Assembly.
11. Stand well away from the Lift and vehicle. Then squeeze and hold in the Hand Lever while at the same
time pushing in and holding the Pressure Relief Valve Handle to slowly lower the Lift all the way down
to the floor.
12. Move the Saddle Pads and Arms inward, out of the path of the vehicle.
13. Disengage the vehicle parking brake. Start the vehicle's engine, and carefully drive the vehicle off the
Lift slowly.
Inspection, Maintenance & Cleaning
Always unplug the Power Cord from the electrical outlet before performing any
inspection, adjustments, maintenance and/or cleaning.
BEFORE EACH USE: Inspect the general condition of the Lift. Check for loose screws, misalignment
or binding of moving parts, broken parts, damaged electrical wiring and hoses, and any other condition
that may affect its safe operation. If abnormal noise or vibration occurs, have the problem identified and
corrected before further use. Do not use a damaged equipment.
DAILY: With compressed air or vacuum, remove all dirt and debris from the Lift. Also, use a detergent
or mild solvent to remove oil and grease from the unit. Then, use a premium quality, machine oil to
lubricate all moving parts.
MONTHLY: With the lift fully lowered, check the level of hydraulic oil in the Reservoir Tank is close to
the Max Fill Line. If not, remove the Fill Cap and add premium quality hydraulic oil until the level of oil
is even with the Max Fill Line. After filling, place the Fill Cap to Reservoir Tank.
Never Add Hydraulic Fluid while Lift is in raised position!!
