Always wear eye protection when operating or
performing maintenance on this tool.
Always turn off the air supply and disconnect the air
supply hose before installing, removing or adjusting
any accessory on this tool or before performing any
maintenance on this tool.
LUBRICATION
Each time a Series 1, 2, 3, 4, W1, W2, W3 or W4 Chipper
is disassembled for maintenance and repair or replacement
of parts, pour about 3 cc of Ingersoll–Rand No. 10 Oil in
the air inlet and operate the tool for 5 seconds to coat the
internal parts with oil.
Weekly, flush the Tool and lubricate immediately
afterwards as instructed in PLACING THE TOOL IN
SERVICE.
Loss of power and excessive air consumption may be due
to wear on the Piston (22) and the bore of the Barrel (23).
This can be determined by checking the Piston diameter at
each end and in the center with a micrometer. If the
diameter at the center is .003" greater than the diameter at
either end, it is proof that the Piston and Barrel are worn.
To correct, lap the Barrel and install an oversize Piston as
instructed below, under Installation of Oversize Piston.
OVERSIZE PARTS
The Piston (22), Nozzle (24) and Inlet bushing (11) can be
furnished oversize as well as standard size. When prop–
erly installed, oversize parts renew the efficiency of the
Chipper as well as lengthen its life. See Installation of
Oversize Piston, Nozzle, and Inlet Bushing on Page 22.
If examination of the Handle (1) indicates that it is not
seating squarely on the Valve Cap (17), reface the handle
seat. Coat the barrel threads with graphite grease or other
rust resisting compound before screwing on the Handle.
DISASSEMBLY
General Instructions
1. Do not disassemble the tool any further than
necessary to replace or repair damaged parts.
2. Whenever grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws to
protect the surface of the part and help prevent
distortion. This is particularly true of threaded
members and housings.
3. Do not remove any part which is a press fit in or on a
subassembly unless the removal of that part is
necessary for repairs or replacement.
4. Do not disassemble the tools unless you have a
complete set of new gaskets and O–rings for
replacement.
