WARNING
READ ALL INSTRUCTIONS BEFORE OPERATING THIS JACK TO AVOID MISUSAGE OR SERIOUS INJURY. FOR MORE
INFORMATION ON THE CORRECT APPLICATION AND USAGE OF THIS PRODUCT CONTACT THE MANUFACTURER.
Caution
Jack is designed for lifting purpose
only
.
It must not be used as a jack stand to hold load for any prolonged period. Do not
move the jack when load is in very high position and is not fixed on saddle stably
.
The jack should move only
on
a hard
level surface. Do not adjust safety valve. When necessary, return jack to
serv
ice
agent for any adjustment. Do not overload
and jack beyond its rated capacity. Do not substitute component parts when jack model is different.
Operating Procedure
Exhausting
•
During shipment and handling, especially after a long storage, air probably gets into the hydraulic system, causing poor lifting
performance
.
Exhaust any air from the system before use
.
Here follow the methods
.
•
Close release valve
(
turn knob clockwise as shown). Loosen the air vent plug on the filler
,
then operate handle until the empty
saddle gets to the highest.
•
Open the release valve (turn knob counterclockwise). While holding the empty saddle down, operate handle rap
i
dly several
times in order to exhaust the air in the system
,
then press the air vent plug tightly.
Lifting
•
Turn the knob clockwise until release valve closes
.
Do not over tighten the va
l
ve
.
•
Place jack directly and centrally under object to be lifted
.
Operate the handle up and down within an angle of 60°
.
The jack can
take up load immediately.
•
While lifting very heavy objects, the angle to operate handle must be w
i
thin the limits of 45° so as to avoid damaging parts with
the rapid increase of the operating force. (full 360orotating pump handle operates in any pos
i
tion)
•
After raising jack to required height: use jack stand(s) to hold load
.
Transmission
•
Fix load tightly on the saddle with chains.
•
Turn the release valve counterclockwise in order to lower the load to lower position (About at the midpoint of the whole lifting
height).
•
The four handlebars on jack (as shown in the diagram) are used to move jack in any direct
i
on on level solid surfaces
.
Saddle Adjusting
•
For safe and proper use
,
the saddle can be adjusted according to the load size and angle degrees while d
i
sassembling (As
shown in the diagram).
•
Loosen the four bolts on saddle, adjust the four retaining plate ass
embl
y parts to proper position, then twist bolts tightly
.
The
saddle side adjustment is within the limits as shown in the specifications
.
•
Adjust the two regulating bolts on the saddle, and then the saddle can be side titled within the limits as shown in the
specifications. The two bolts must be adjusted simultaneously and harmoniously in order to let the saddle stay in required angle
and not away.
•
Turn the adjusting hand wheel under saddle
.
Then the saddle can be titled withi
n
the limits from forward to back as shown in the
specificat
i
ons.
