4. cradles
Install a cradle and pulley bar on top of each front H-unit and another
cradle on the rear H-units using:
8 – 1/2" x 3 1/2" hex bolts
8 – 1/2" nylon lock nuts
Attach the cradle spreader tubes between the front and rear H-units using:
8 – 3/8" x 7" hex bolts
8 – 3/8" at washers
8 – 3/8" nylon lock nuts
Install the winches on the outside mainframes using:
4 – 3/8" x 4 hex bolts
8 – 3/8" at washers
4 – 3/8" nylon lock nut
CAREFULLY thread the 25" red wheels onto the winch shafts. The wheels
should be able to thread on and o the shaft easily. This is the action that
activates the brake mechanism.
Turn the wheel clockwise and you should hear a clicking sound, this
means the brake is working. This raises the lift and keeps it raised wherever
you stop.
Turn the wheel counter clockwise and the brake is released allowing the
lift to lower.
To keep the wheel from coming o the shaft fasten using:
1 – winch spring
1 – 1/2" jam lock nut
Tighten the nut just until 1 or 2 threads of the shaft are visible while prevent-
ing the winch shaft from turning.

NOTE
The wheel needs to thread on and o
the shaft to activate the brake. This
shaft should be greased yearly to
ensure proper operation.
Extreme care should be taken not to
cross thread and damage the threads
on the wheel hub. This will void your
warranty.

Attach the loop end of the cable to the mainframe opposite the winch
using:
1 – 3/8" x 4 hex bolt
2 – 3/8" at washers
1 – 1/2" at washer
1 – 3/8" nylon lock nut
String the cable inside the pulley bar as shown in the exploded view (page 6).
Secure it to the winch following the instructions included with the winch.
Attach the vinyl wrapped aluminum bunks to the front and rear cradles
using:
8 – 5/16" x 1 hex bolts
16 – 5/16" x 2-1/2" hex bolts
24 – 5/16" lock nuts
For most uses bunks should be placed approximately 18" apart. Make sure
the bunk adjustment channels are on the outside of the lift as shown.
Now tighten all nuts and bolts, except the ones from Step 3 and 4 that must
be free to allow the H-units to pivot.
Install the 10 plastisol caps, 2 at the top of each mainframe and 6 on the legs.
Move your lift into the water and adjust its legs so that the lift is level. The
legs can be removed to lower the lift if the water is very shallow.
Adjust the bunk height just high enough so your craft's bottom will not hit
the cradle.
Adjust the bunk angle to conform to the boat bottom and tighten the bolts
so that the bunks no longer move.
The installation is now complete.
NOTE
Never over crank the winch. Once
the lift has reached its highest
point, further cranking will damage
the lift.

important
A. Grease the winch shaft annually. The red wheel must be able to thread and unthread easily in order for the braking mecha-
nism to work properly.
B. Your LSP PWC Lift will only protect your personal watercraft if the craft is lifted well above the level of the water. In larger lakes
or during storms, large waves may lift the craft from the lift or tip the lift over, causing damage both to the craft and the lift.
You must take precautions to protect your craft and lift from these conditions. If your craft suers damage from high waves,
LSP, Inc. will not accept responsibility for such damage.
C. Inspect your lift often for signs of wear or improper operation. Be aware of normal cranking force. Any increase in cranking
force is a sign that something is wrong. DO NOT USE the lift if any parts are worn or damaged, replace immediately.
D. Pay attention to the condition of your cable. A frayed or rusted cable can lead to failure of the lift. Replace it immediately.
Greasing the cable, especially where it enters the winch, can extend its life.
E. A second caution decal is provided in the accessories box. If after assembly the decal is not easily seen then install the extra
decal so that anyone using the lift can read it. NEVER let anyone operate the lift unless they are familiar with all safety rules.
F. NEVER let anyone play on, around, or under the lift.
hints
A. Place your lift in the deepest water you can, your lift will operate most easily at the top of its lifting range.
B. Deep V hulls may be accommodated by moving the front of the bunks closer together and leaving the back farther apart to
provide stability.
C. In deep water ? If you have a deep lake and are in need of longer legs, LSP, Inc. oers 4 foot long legs for your PWC Lift. Ask
your dealer for details or call us at 517.639.3815.
D. Greasing the cable where it wraps around the winch drum will increase cable life.
