PREPARATION PROCEDURES
Each unit, as shipped, has no special unpacking or
assembly 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 a grinding wheel a unit may be put to use.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated flow meter and pressure gauge,
check that the hydraulic power source develops a
flow of 7-10 GPM/26-38 LPM at 1500-2000 psi/105-
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 hydraulic circuit matches the tool for
open-center (OC) or closed-center (CC) operation.
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 fittings and
fasteners tight.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free
to travel between the "ON" and "OFF" positions.
CHECK GUARD ASSEMBLY
1. Inspect the wheel guard assembly for cracks and
other structural damage.

OPERATION

Never over-tighten the grinding wheel by impacting
the wrench with a mallet or hammer. Sufficient
torque is attained by hand-tightening the wheel
with a strap wrench or for wheels secured with
capscrews, hand tightening with a socket wrench
Note: Use 6-inch diameter up to 3-inch thick (Type 6
for USA/Type 36 for CE) grinding wheels with a 5/8-
11 threaded arbor hole. Only use grinding wheels
which comply with ANSI B7.5/ISO 525, 603.
2. Depress the push lock (6) and screw the grinding
wheel onto the main shaft (13) and tighten using a
strap wrench.
3. Adjust guard to desired height.
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 grinder. It is a
good practice to connect the return hose first and
disconnect it last to minimize or avoid trapped
pressure within the grinder motor.
3. Observe flow indicators stamped on hose couplers
to be sure that oil will flow 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 difficult to
connect. When possible, connect the free ends of
operating hoses together.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Always start the grinder with the grinding wheel
away from the work surface.
3. Move the hydraulic circuit control valve to the "ON"
position.
4. Disengage the safety thumb latch (42) and squeeze
while depressing the push lock.
