OPERATING THE HYDRAWEDGE:

ALWAYS USE CORRECT TYPE OF WEDGE!
Two types of wedges are available for different types of uses. The standard wedge can be used for all applications except where the unit is used flat against the floor. Where HydraWedge must be in contact with the floor, always use the offset wedge! This restricts the load to the wedge plates, and keeps load from bridging between wedge and plate arm, which would result in a bent piston.


OPERATION
HydraWedge is equipped with two sockets located on top of unit near the rear cover plate. Each socket actuates a pump; one of which extends the piston, the other which retracts the piston to its original position. IMPORTANT! when extending or retracting the main piston, it is absolutely necessary for the pump handle to be placed as deep in the socket as possible, the shoulder of the pump handle bottoming in the socket hole. The smaller shaft diameter should extend completely through the hole. Before actuating the pump, always place the unused socket in the vertical position; otherwise the piston will not move! To extend the piston, insert the pump handle in the right-hand socket(facing the rear end cap) and pump back and forth. Pumping the left-hand socket retracts the piston.

FAST RETRACTION
The main piston can be rapidly retracted without pumping. Place both pump and sockets in vertical position and spread plates, exposing wedge. Grasping HydraWedge housing, push wedge against floor or any solid object. Piston will slide freely into cylinder.

Caution: When attatching or removing the wedge, never use any type of wrench or clamp on the main piston, as any damage to the surface will cause injurious wear and oil leakage in HydraWedge!



SERVICING THE HYDRAWEDGE:
SERVICING
Your HydraWedge will deliver far more wedging force, smooth, safer, and with less physical effort than the old method of wedge and hammer. However, to get the most from your HydraWedge, always see that it is properly serviced.

ADDING OIL
When piston will not extend to full stroke, oil should be added. To add oil, first make sure piston is fully retracted. Remove the 1/8 inch pipe plug in oil filler (11) at rear of the unit behind the sockets. Pour clean, good grade SAE 20 motor oil in filler, simultaneously pumping the handle. Pumping will advance the piston and pull the oil into the chamber. Continue adding oil until piston is fully advanced, then add a small surplus of oil, completely filling the port. Loosely replace the pipe plug, allowing an escape passage for entrapped air and surplus oil. Now place handle in opposite socket and retract the piston by pumping. When piston is fully retracted, tighten pipe plug, sealing oil filler.

GREASING THE WEDGE
Wedge surfaces and metallic plates should always be kept greased. Use any good grade cup grease. This attention reduces friction, insures easier operation and greatly reduces pumping effort.

ADJUSTING PLUNGER PACKING
Packing around pump plungers can be adjusted by lifting plungers as high as possible, exposing jam nut (75-1037). Remove nut with spanner. Tighten packing by adjusting nut immediately below jam nut and replace jam nut tightening securly.

TROUBLE SHOOTING
If unit refuses to pump, inspect check valves (73-1013) for contamination. These valves can be pulled by removing pipe plug immediately in front of the socket being pumped.

After cleaning, if unit still refuses to operate, remove back cover and inspect ball check (75-1014) for contamination.

When back cover is removed, check diaphragm for proper seating. A new diaphragm usually saves time and insures original operating efficiency.
