PRE-OPERATION PROCEDURES
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated ow meter and pressure gauge,
check that the hydraulic power source develops
a ow of 7–10 GPM/26–38 LPM at 2200–2300
psi/152–159 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 in-
stalled. 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 ttings and fasten-
ers tight.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free
to travel between the ON and OFF positions.
CHECK GUARD WELDMENT
1. Inspect the wheel guard weldment for cracks and
other structural damage.
INSTALLING AND REMOVING
GRINDING WHEEL
NOTE:
Use 6 inch diameter up to 3 inch thick (Type 6 for
USA) grinding wheels with a 5/8-11 threaded arbor
hole. Only use grinding wheels which comply with
ANSI B7.1, B7.5/ISO 525, 603.
READ AND BECOME FAMILIAR WITH THE SECTIONS
IN THIS MANUAL ON SAFETY PRECAUTIONS, TOOL
STICKERS AND TAGS, HYDRAULIC HOSE REQUIRE-
MENTS, HYDRAULIC REQUIREMENTS, AND PRE-
OPERATION PROCEDURES BEFORE USING THIS
PRODUCT.
1. Unscrew the two nuts (98) which secure the guard
weldment (95) to the frame and remove the guard
weldment.
2. Install the grinding wheel until it comes in contact
with the drive ange.
3. Using the wrench (89) provided, place it on the
ats of the drive ange. Place a strap wrench on
the grinding wheel and then tighten by gripping and
turning the strap wrench while holding the wrench
provided.
4. Replace the guard weldment.
Never over-tighten the grinding wheel by impacting
the wrench with a mallet or hammer. Su󰀩cient
torque is attained by hand-tightening the wheel with
a strap wrench while securing the drive ange with
the wrench provided.
ADJUST WHEEL FLANGES TO FIT RAIL
The wheel anges may be adjusted to t the width of the
rail by removing one or more of the washers.
CONNECTING THE 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 prac-
tice to connect the return hose rst and disconnect
it last to minimize or avoid trapped pressure within
the grinder motor.
3. Observe ow indicators stamped on hose couplers
to be sure that oil will 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 di󰀩cult to connect.
When possible, connect the free ends of operating
hoses together.
OPERATION

PG10 User Manual ◄ 11
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Always start the grinder with the grinding wheel
away from the work surface by turning the hand
wheel counter clockwise to raise the wheel.
3. Move the hydraulic circuit control valve to the ON
position.
4. Squeeze the trigger momentarily. If the grinder does
not operate, the hoses might be reversed. Verify
correct connection of the hoses before continuing.
5. Start the grinder and move the grinding wheel to the
work surface by turning the hand wheel clockwise.
6. Grind a small amount of material at a time adjusting
the grinding wheel as necessary by turning the hand
wheel.
NOTE:
If the grinder is not loaded against a work surface
when the trigger is released, the wheel will take 5-10
seconds to come to a complete stop. Avoid uninten-
tional contact of the grinding wheel during the coast
down period.
COLD WEATHER OPERATION
If the grinder is to be used during cold weather, preheat
the hydraulic uid at low engine speed. When using the
normally recommended uids, uid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes) be-
fore use.
Damage to the hydraulic system or grinder can result
from use with uid that is to viscous or too thick.
OPERATION

12 ► PG10 User Manual
1. The gears and bearings in the ram, spindle, and
housing assemblies should be regreased every 6
months or 500 hours. This procedure must be ac-
complished by a trained technician.
2. After each servicing, measure the spindle speed
(rpm – revolutions per minute) at 12 GPM/45 LPM
input. The nominal speed is 4000, not to exceed
6000 rpm. This procedure must be accomplished by
a trained technician.
3. Inspect the spindle and drive ange for signs of
wear or damage. Run out should not exceed .004
in./.1 mm TIR on threads or .002 in./.05 mm TIR on
arbor diameters and faces.
4. Check hoses and ttings weekly for any evidence of
leakage, cover wear, cracking or cuts. If any of these
defects are found, discontinue use of the tool imme-
diately and have the defects repaired or replaced by
a trained technician.
PREVENTATIVE MAINTENANCE

PG10 User Manual ◄ 13
• Make sure all couplers are wiped clean before con-
nection.
• The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydrau-
lic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hy-
draulic system.
• Always store the tool in a clean dry space, safe from
damage or pilferage.
• Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the IN port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse cir-
cuit ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by STANLEY.
Supply hoses must have a minimum working pres-
sure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) in
this manual for correct ow rate and model number.
Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning
stickers and tags legible.
• Tool repair should be performed by experienced
personnel only.
• Make certain that the recommended relief valves
are installed in the pressure side of the system.
• Do not use the tool for applications for which it was
not intended.
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.

PROBLEM CAUSE SOLUTION
Grinder does not run. Hydraulic power source not
functioning.
Check power source for proper ow
and pressure (7–10 GPM/26–38
LPM @ 1500–2000 psi/ 105–140
bar.
Couplers or hoses blocked. Locate and remove restriction.
Hydraulic motor failure. Inspect and repair.
Hydraulic lines not connected. Connect lines.
Grinder operates too slow. Hydraulic motor speed to slow. Check power unit for proper ow
(7–10 GPM/26–38 LPM).
High back-pressure. Check hydraulic system for
excessive back-pressure (over 250
psi/17 bar).
Couplers or hoses blocked. Locate and remove restriction.
Oil too hot (above 140 °F/60 °C) or
too cold (below 60 °F/16 °C).
Check hydraulic power source for
proper oil temperature. Bypass
cooler to warm oil or provide cooler
to maintain proper temperature.
Relief valve set too low. Adjust relief valve to 2100–2250
psi/145–155 bar.
Hydraulic motor worn. Inspect, repair or replace.
Flow control malfunctioning. Have ow control serviced at an
authorized STANLEY service
center.
Grinder operates too fast. Flow control malfunctioning. Have ow control and valve body
serviced at an authorized STANLEY
service center.
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.
When diagnosing faults in operation of the grinder, always check that the hydraulic power source is supplying the
correct hydraulic ow and pressure to the grinder as listed in the table. Use a owmeter known to be accurate.
Check the ow with the hydraulic oil temperature at least 80 °F/27 °C.
