ASSEMBLY INSTRUCTIONS
NOTE: An assistant is required to assemble this unit and
minimize the potential hazards and/or injury.
1. Line up the holes on the Caster Wheels (29) with the
matching holes on the Base (7) and attach with Bolts
(32).
2. Slide the right Front Leg Extension (wheel angled
slightly inward) (1) into right side of Base (7) until the
pin hole aligns with the pin hole on base. Slide Pin (3)
through hole in leg extension and base and secure pin
with Clip (8). Repeat this procedure for the left front
leg extension.
3. With the help of an assistant, install the Upright Mast
(10) onto the base using Bolts (6), Washers (5) and Nuts
(4). Install the Mast Braces (9) onto the base using Bolts
(6), Washers (5) and Nuts (4). Align holes at the upper
end of the Mast Braces with the second hole from the
top in the Upright Mast using Bolt (14), Washer (15)
and Nut (16). Once aligned, tighten the bolts securely.
4. Install the Hydraulic Ram (13) to the support bracket
on the Upright Mast using Bolt (11), Washer (15) and
Nut (16). Once secured, lean the hydraulic ram against
the Upright Mast temporarily.
5. Install the Boom (25) on top of the Upright Mast and
secure with Bolt (20), Washer (21) and Nut (22).
6. Align and install the top of the hydraulic ram into the
welded fork on the boom and secure with Bolt (23),
Washer (15) and Nut (16).
7. Slide Boom Extension (26) into boom and secure with
Slide Pin (24) and secure with Clip (8).
8. Install the Hook and Chain (27) at the end of the boom
extension using Bolt (28), Washer (5) and Nut (4).
OPERATING INSTRUCTIONS
1. Lock the boom in place for the proper weight marking
using the lock pin BEFORE APPLYING THE LOAD TO THE LIFT. Do not exceed the rated capacity and travel limits
of the equipment.
2. Use appropriate levellers, slings or chains around the
load capable of sustaining the load before using the
hook to lift it. Make sure that the latching mechanism
is working properly before lifting or moving the load.
3. Once the load is securely hooked in place, lift the load
by turning the release valve clockwise until closed,
and pumping the jack until the load is clear of any
obstruction. Move very carefully avoiding slopes in
the direction of travel. Avoid sudden or swinging
movements of the load. To lower the load, turn the
release valve on the hydraulic jack counterclockwise
very slowly.
TROUBLE SHOOTING
SYSTEM AIR PURGE
1. Turn release valve counterclockwise one full turn
to open.
2. Pump handle eight full strokes.
3. Turn release valve clockwise to closed position.
4. Pump handle until the lift arm reaches maximum
height and continue to pump several times to remove
trapped air in the ram.
5. Turn release valve counterclockwise one full turn to
open and allow lift arm to retract.
6. Close release valve and check for proper pump action.
It may be necessary to perform the above move more
than once to assure air is evacuated totally.
9. Slide the Handle (12) on the socket on the hydraulic
ram.
