PREPARATION FOR INITIAL USE
Each unit as shipped has no special unpacking or assem-
bly requirements prior to usage. Inspection to assure the
unit was not damaged in shipping and does not contain
packing debris is all that is required. After installation of
hoses and couplers a unit may be put to use.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated fl owmeter and pressure gauge, check
that the hydraulic power source develops a fl ow of 3-9
gpm/11-34 lpm at 1000-2000 psi/70-140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2100-2250 psi/145-155 bar
minimum.
3. Check that the tool is designed for the hydraulic system
type open-center (OC) or closed-center (CC) operation).
See the parts illustration for location of marks which identify
the tool as a OC or CC tool.
CHECK TOOL
1. Make sure all tool accessories are correctly installed.
Failure to install tool accessories properly can result in
damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all fi ttings and fasteners
tight.
4. The tool must be periodically inspected for electric insu-
lation quality to ensure that it has kept its original factory
quality per OSHA 100 kV/A requirement.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free to
travel between the "ON" and "OFF" positions.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth before
making connections.
2. Connect the hoses from the hydraulic power source to
the hose couplers on the tool. It is a good practice to con-
nect the return hose fi rst and disconnect it last to minimize
or avoid trapped pressure within the saw motor.
OPERATION
3. Observe fl ow indicators stamped on hose couplers to
be sure that oil will fl ow in the proper direction. The female
coupler is the inlet coupler.
NOTE: The pressure increase in uncoupled hoses left
in the sun may result in making them diffi cult to con-
nect. When possible, connect the free ends of operat-
ing hoses together.
