adjustable handle (44).
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 difcult to
connect. When possible, connect the free ends of
operating hoses together.

OPERATION
6. Grind a small amount of material at a time adjusting the grinding wheel as necessary by turning the
handwheel.
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 unintentional 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) before use.
Damage to the hydraulic system or grinder can result
from use with uid that is to viscous or too thick.
PREVENTATIVE MAINTENANCE
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 accomplished 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. Runout 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 immediately and have the defects repaired or replaced by
a trained technician.
5. To grease between main housing bore (item 73) and
the ram outer diameter (item 26) use CAUTION only
one to two pumps of grease are required at these
locations, excess grease will lockup feed assembly
(See gure 4 below).

TOOL PROTECTION & CARE
NOTICE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the
“OFF” position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hydraulic 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
Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) 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.
