Before fIrSt uSe
4.1.1.
Assemble handle by sliding the two parts together and rotating until the locking pin clicks into position. Partially unscrew knurled
nob (fig1) until handle slides fully into socket. Tighten the knurled nob to lock handle in place.
4.1.2.
Before using jack for the first time, purge the hydraulic unit in order to eliminate any air in the system. Turn handle anti clockwise to
open release valve.
4.1.3.
Pump for 30 to 40 seconds. When complete, close the release valve by turning the handle clockwise.
4.1.4.
Place a few drops of hydraulic jack oil on pump piston and pump handle several times to distribute oil. Thoroughly lubricate moving
parts.

Commence pumping handle up and down using maximum strokes until the jack saddle reaches the vehicle manufactures jacking
point. Check the jacking point is centrally located on the saddle and raise the vehicle.
4.3.3.
Should the jack become overloaded, a safety excess pressure valve will open, and stop the vehicle from lifting.
WarnInG! The jack is a lifting device only and must not be used to support the load. Use correctly rated axle stands to support the
‰
load.

Keep the jack clean and lubricate all moving parts with oil on a regular basis.
5.3.
Before each use check for broken, cracked, bent, or loose parts, or any visible damage to ram, pump, saddle, lifting arm, frame and
all parts including nuts, bolts, pins and other fasteners. If any suspect item is found remove jack from service and take necessary
action to remedy the problem.
