Operation - Stanley CH18 User Manual

PREPARATION PROCEDURES
The tool, as shipped, has no special unpacking or
assembly requirements prior to usage. Inspection to
assure the tool was not damaged in shipping and does
not contain packing debris, is all that is required.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated flowmeter and pressure gauge,
check that the hydraulic power source develops
a flow of 7–9 GPM/ 26–34 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) operation.
CHECK TOOL
1. Ensure all tool accessories are correctly installed.
Failure to properly install tool accessories 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.
INSTALL TOOL BIT
The tool accepts standard 0.580 in hex x 2-1/2 inch long
hex shank tool bits.
TO INSTALL A HEX SHANK TOOL BIT
1. Push in the retainer, insert the hex shank tool bit and
move the retainer back into locked position. Note
the orientation of the particular tool bit that is being
installed.
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. Connect the return
hose first and disconnect it last to minimize trapped
pressure within the tool.
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.

OPERATION

OPERATING PROCEDURES
1. Observe all safety precautions.
2. Move the hydraulic circuit control valve to the "ON"
position.
3. Place the tool bit firmly on the surface you are to
work on.
4. Squeeze the trigger to start the tool. Adequate down
pressure is very important.
Do not use the CH18 underwater, unless designated
COLD WEATHER OPERATION
If the tool is to be used during cold weather, preheat
the hydraulic fluid at low engine speed. When using the
normally recommended fluids, fluid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes)
before use.
STORAGE
1. Disconnect the tool from the hydraulic power source.
2. Remove the tool bit and spray the tool bit retainer
area with WD-40™, inside and out.
3. Wipe clean and store in a clean, dry place.
UNDERWATER MODEL
PREVENTATIVE MAINTENANCE
After each use, the movable portions of the tool that
were exposed to water should be flushed with a water
displacing oil, such as WD-40™. Remove any remaining
water and debris as follows:
1. Turn the tool upside down (without the tool bit) and
spray oil throughout the inside of the retainer nose
including the retainer cap and any moving parts, also
spray any of the exposed piston area to displace
any remaining water.
2. Spray oil into the On/Off valve trigger slot area.
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before
storing away.
IMPORTANT
for underwater use.
