PREPARATION
(cont.)
NOTICE: The lift is equipped with a 1/4" NPT air coupler.
If installing a different air coupler, ensure thread tape
or compound is used when servicing connections. To
ensure dependable, trouble free operation an inline air
dryer and oiler is recommended.
6. Pump mechanism should operate smoothly before
putting jack into service. Replace worn or damaged
parts and assemblies with Polaris authorized
replacement parts only.
Bleeding/Venting Trapped Air
With the Release Knob in the OPEN position (step 3b,
pg. 3) and Ram fully lowered, locate and remove the oil
filler screw. As screw is removed, pressurized air may
be heard escaping from the reservoir.
! CAUTION: Reservoir may be under pressure and
hydraulic oil may be expelled.
This means trapped air has been successfully removed
from the system. With Lift Pedal in the sleeve, pump 6
to 8 full strokes. This will help release any pressurized
air still trapped within the reservoir. Oil level should be
even with the bottom of the oil filler hole. Reinstall the
oil filler plug/screw.
ASSEMBLY
1. Install Hydraulic Unit on receiver and secure with
provided M8 x 1.25 bolts (ref. Figure 2).
2. Insert Ram pin through Ram and Ram brackets on
crosshead assembly, then install cotter pin.
3. Insert Release Knob through Release Knob guide
and attach to Hydraulic Unit with screw and nut pro-
vided.
4. Insert Lift Pedal into Sleeve and attach with supplied
bolt.
5. Install Positioning Handle into frame and secure using
the provided pins (2).
6. After assembly, ensure that lift rolls, lifts and locks,
and that pump operates smoothly before putting into
service. Familiarize yourself with how Height Lock-
ing Lever, Lift Pedal, and the Height Unlocking Lever
operate prior to loading lift. Replace worn or damaged
parts and assemblies with
parts only (ref. Replacement Parts, pg. 6). Lubricate
as instructed in Maintenance Section.
OPERATION
1. Line up vehicle undercarriage with saddle.
2. Lift saddle to just before contact to ensure the contact
area will be in a proper location.
authorized replacement
WARNING: Use only on hard, level surfaces ca-
!
pable of sustaining rated capacity loads.
3. Close Hydraulic Release Valve and carefully pump
jack until vehicle reaches desired height. Final height
must correspond with the locking teeth on the Height
Locking Lever.
4. Carefully turn the Release Knob counterclockwise until
the Lift Platform engages the Height Locking Lever,
then close the Release Knob by turning it fully clock-
wise. Do not work around or under load unless
Height Locking Lever is properly engaged.

CAUTION: Clear all tools and personnel before
lowering load. Only attachments and/or adapters
supplied by the manufacturer shall be used with
this device.
6. To lower the Lift Platform pump the Lift Pedal several
times to disengage the Height Locking Lever, then
depress the Height Unlocking Lever pedal. Carefully
turn the Release Knob counterclockwise to lower the
load slowly.
MAINTENANCE
Keep lift clean and well lubricated. Apply a couple of
drops of light machine oil to all pivoting joints as needed.
Thoroughly wipe up excess oil.
NOTICE: Use premium quality 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 failure of the jack and the po-
tential for sudden and immediate loss of load.
Adding oil
1. To check hydraulic oil level, unload lift, lower Lift Plat-
form completely, then remove Hydraulic Unit from lift.
Place Hydraulic Unit upright on a stable, level surface.
