Hi-Force JCS Jacks feature 2 built in safety devices to ensure safe operation and to protect the jack from
damage. They are as follows:
An internal (factory set) pressure relief valve to prevent over-loading. This limits the load that may
be lifted to a maximum equal to the equipment rated load + 10%.
An integral stop ring to limit maximum stroke and prevent over-stroking of the piston.
operate the pump without an external load present, to prevent damage/injury.
6.1 To Lift or Push a Load
Using the key on the end of the operating lever, turn the release valve screw clockwise to close it.
NOTE:
Excessive tightening is not necessary and will lead to component wear.
Put the operating lever into the socket on the pump mechanism and operate the pump. The piston
will rise and lift/push the load. When the piston reaches full stroke the stop ring prevents the piston
from rising further.
If you need to raise the load further than the rated stroke of the jack. Mechanically support the load
in its raised position, then retract and remove the jack. Using a suitable support material (eg steel
plate) raise the level of the jack and continue with the lift.
ALWAYS remove the operating lever from the jack when not in use.
6.2 To Lower the Load
Whenever possible, wipe the piston clean before lowering.
Use the key on the end of the operating lever to turn the release valve screw anti-clockwise and
open it. Opening the release valve SLOWLY will control the rate of lowering.
WARNING:
NEVER turn the release valve quickly when there is a load on the jack. The load will fall
uncontrolled and may lead to personal injury or property damage.
DO NOT overload the jack during lowering.
JCS jacks are fitted with a return spring, so the piston will retract even under no-load.
