arm is at foll down position. If lacking oil, remove vent plug located

under cover plate. Fill with oil to correct level and install and tighten

the plug. Close release valve and pull lifting arm up to its full height.

Then open release valve and by stepping on saddle. Force it to lower

as rapidly as possible. Repeat this operation three or four times.This

procedure will thoroughly flush the valves and assure complete

working order. Close release valve tightly. Try jack under load.

b) The jack may have air trapped in the system. Open release valve.

Pump handle6full strokes. Close release valve and try jack again.

c) O-ring seat for pump may be worn: this will happen only after

months of service. A new O-ring seal or a complete new piston can

be purchased and easily installed.

Release valve may be held open by dirt on seat. Flush by pulling

lifting arm up and down several times while release valve i s open.

If necessary, the release valve may be removed for cleaning the valve

and valve seat.

2.If Jack Lowers Under Load

a) The discharge valve may be held open by dirt on ball seat: When a

dirty discharge valve or ball seat exists, the jack may lower quickly,

causing handle to fly back with force. This is caused by the oil

rushing back into the pump chamber through the open ball seat,When

this happens, it is advisable to repeat procedure l-a before going

through the partial disassembly of the hydraulic unit, The discharge

valve is located at the bottom of ram cylinder there isascreen

washer. This must b e removed carefully and if damagedanew one

must be fitted. NOW remove the discharge valva ball and clean valve

seat.Wipe ball and replace and reseat. Use "diameterl X3" long
