1. Spare Parts List and Exploded Drawing

Trouble shooting

Problem

Cause

Decreased

Air leakage in hoses,

penetration rate

couplings

Shank sleeve

Air leakage due to worn

piston/cylinder

Air leakage due to worn

guide sleeve/pilot guide

Insufficient feed

Piston rod seal (in pusher

force

leg) worn or deformed

O-rings on pusher leg

coupling worn or deformed

Poor rotation

Splines of the rifle nut worn

Splines of the rifle bar worn

down

Splines on the piston worn

down

The toothing in the ratchet

housing is worn out

The toothing in the ratchet

wheel is worn out

Chuck nut worn out

Pawls worn

Uneven running

Piston has seized in the

guide sleeve or the piston

guide

Dirty or damaged main

valve. Caused by impurities

or foreign matter entering

the drill with the compressed

air

Freezing. Caused by leakage

in the flushing system or

by excess water in the

compressed air or by

excessive water pressure

Solution

Change packings, and where

required, change parts in the

throttle valve

Check the shank sleeve for

excessive wear. Replace if

necessary.

Replace the piston and/or cylinder

Change the worn part

Change the seal

Change the o-rings

Replace the rifle nut if the splines

are worn

Replace the rifle bar when needed

Replace the piston when needed

Replace the ratchet housing if the

tooth housing is so worn that the

pawls have difficulty catching

Replace the ratchet wheel if the

toothing is so worn that the pawls

have difficulty catching

Replace the chuck nut if the splines

have been worn to 1/2 of the spline

width

Replace all pawls, all pawl springs

and all pawl pins

Replace the guide sleeve/piston

guide. If required, polish the piston.

Check the piston for heat damage

such as blue colouring and/or

fissures. If it is damaged in this

way, replace the piston as well

Clean and polish the valve so that

it seals against the corresponding

cylindrical and plane sealing

surfaces. If this is not possible

because the defects are too serious,

the valve must be replaced

Check the flushing tubes and seals

and the water pressure. Drain water

from the compressed air system. If

the problem continues,

fit a water separator in the airline

system.
