5. INSTRUCTIONS OF USE
1. Lifting the load
Before lifting an assembly, check the vehicle is fully immobilised on a flat and horizontal surface (1). The hydraulic pit jack must be on a stable
surface void of greasy compounds. Close the valve (5) by turning it clockwise until it is locked (not too tight). Pump (6).
Continue this pumping operation until the position required is reached.
2. Lowering the load
Turn slowly the valve (7) counter-clockwise and remove the hydraulic pit jack. The speed of this action is adjusted according to the rate the valve
is turned.
6. OPERATING INSTRUCTIONS
1. Roll the hydraulic pit jack into position and pump the lift foot pedal until adapter reaches desired height.
NOTE: Follow vehicle manufacturer's recommended procedures for removing the load as outlined in vehicle service manual or repair guide.
2. Carefully center load on adapter. Ensure the load's center of gravity is centered on the adapter and the setup is stable and secure.
NOTE: Before lowering load check to ensure all tools and personnel are clear and it is safe to lower the load.
3. Slowly and carefully turn the release valve counterclockwise (never more than half turn) to lower the load to its lowest possible position.
WARNING! Dangerous dynamic shock loads are created by quick opening and closing the release valve when the load is being lowered.
The resulting overload may cause hydraulic system failure which could cause property damage and/or severe personal injury.
4. If necessary, carefully and slowly move the hydraulic pit jack.
5. Transfer load immediately to appropriate support device for service or repair.
7. MAINTENANCE (§ 7.1.3 de l'EN 1494+A1)
Proper maintenance of the hydraulic pit jack will ensure its durability.
Service and repair hydraulic pit jack in compliance with the manufacturer's instructions.
Important: Entrust maintenance and repair of the hydraulic pit jack to skilled personnel, trained in hydraulic systems used in these devices.
When the hydraulic pit jack is no longer used, maintain it in the lower position, with the valve closed. Keep the hydraulic pit jack and handles clean.
Lubricate moving parts regularly.
Bleed the hydraulic system (§ INSTRUCTIONS BEFORE USE)
- To check or top up the oil level, fully retract the piston, remove the filling plug and empty the oil into a container. Once the hydraulic pit jack is in
the horizontal position, fill the volume with appropriate oil matching the indications supplied for the model. The table of parts provided here indicates
the volume of oil necessary. Prevent foreign material from contaminating the new oil. After a period of heavy use, change the oil to extend the lifetime
of the hydraulic pit jack.
Important: Excess oil can make the hydraulic pit jack inoperative.
Only use hydraulic oil ISO VG
- Check that the supply hoses are neither damaged, nor bent, nor worn. Do not install any load below them, or place them near sources of heat or
hit them. To ensure proper operation of the equipment or avoid any breakage, the hoses must be as straight as possible, without twists, bends or
sharp angles. Also ensure that the connection is made properly. Never disconnect a hose without depressurizing the system first.
- Use only original parts.
- Never modify an hydraulic pit jack.

Symptom
Hydraulic pit jack cannot lift load or pump feels
spongy.
Hydraulic pit jack lift load, but cannot hold.
Hydraulic pit jack can not lower completely.
Hydraulic pit jack cannot reach maximum height.
- If the hydraulic pit jack is not used, fold the lifting arm completely to prevent any corrosion. If applicable, apply an anti-corrosion product to the
piston.
- Store the hydraulic pit jack in a dry and clean location, away from children.
- When the hydraulic pit jack is not being used, drain the oil and hand the latter to an approved agent, then dispose the hydraulic pit jack as per
local regulations.
- To order the repair kit, comprising hydraulic pit jack O-rings and pads, as well as all spare parts, please use the reference in the table.
GUARANTEE
Type D = 2 years. See the general conditions in the FACOM price list.
