INSTRUCTIONS
1. Elevation
A. Put the rod into the saddle, and tighten the seat screw which should be plunged to the
location hole in the rod.
B. Raise the control rod to the upper function and pull the handle up and down, repeated
times while the arm starts to rise. The arm tray should be focused to the center of the
load before it reaches the required height.
C. In case that the tray is too low from the load. Please use the foot pedal so as to get to
the load fast.
2. Discharge
Turn the handle to the right position in the bow shaped hole and pull the control rod down
to the low fulcrum, and turn it around to the notch so as to start the gear to bleed oil, and

MAINTENANCE
IMPORTANT: Both the maintenance (7) and repair of the jack may only be performed by
qualified persons, who have sufficient knowledge of the hydraulic systems used in these
devices as a result of their training and experience.
Keep the jack clean and lubricate all moving parts at regular intervals (8), which must be
clean and protected from aggressive conditions at all times.
Only original spare parts should be used.
Prior to each use, check for bent, broken, cracked or loose parts. If it is suspected that the
jack has been subjected to abnormal loads or has suffered any knocks, withdraw it from
service until the problem has been rectified.
If the oil level needs to be checked or refilled, with the piston fully retracted, remove the
filler plug and drain its contents into a container. With the jack in a horizontal position,
proceed to introduce the necessary volume. Make sure that no dirt enters with the new oil.
Following a period of prolonged intensive use, it is recommendable to change the oil in
order to extend the useful life of the jack.
IMPORTANT: An excess of oil to the volume required may render the jack inoperative.
Only use hydraulic oil (8), type HL or HM, with a maximum ISO grade of cinematic viscosity
of 30 cST at 40º, or an Engler viscosity of 3 at 50ºC.
EXTREMELY IMPORTANT: NEVER USE BRAKE FLUID.
