This manual covers the following models.
GM C/S100 Compact Chipper/ Shredder with interchangeable cassettes
Optional 14HP or 18HP (electric start) Briggs and Stratton Vanguard engines
GM C/S100TM tractor mounted version with gearbox and power take off (pto) shaft
instead of engine.
Accept where otherwise stated alternative paragraphs and illustrations for engine driven
and tractor mount versions are marked (a) and (b) respectively.
The information in this manual is correct at the time of publication. However, in the course
of development, changes to the machine specification are inevitable. Should you find any
information to vary from the machine in your possession please contact your GreenMech
dealer for up to date information.
The manual may contain standard and optional features and is not to be used as a
machine specification.
PURPOSE
CAUTION! This machine is designed solely to chip wood and must not be
used for any other purpose. The machine should only be used by trained

Noise
Noise levels vary depending on type of material being processed. Also duration of
operation is variable. Noise emission tests have been carried out and the guaranteed
sound power level is displayed on the CE plate as follows: Lwa 120dB(A)
Minimise noise by slowing to idle or stopping the engine whenever chipping is not in
progress.
CAUTION! Operators must wear appropriate ear protection. Bystanders must be
kept away from proximity of machine.
Lifting Points
Ensure infeed chute is folded in and secured for transport. Sling from tubular handles of
fixed section of infeed chute and lifting point on discharge chute.
Drawbar and hitch or three point linkage
(a) Ring type hitch (b) tractor three point linkage.
CAUTION! Ensure that the towing vehicle or tractor is correctly suited to the machine

correct length for the tractor make and
model. See Section 4.4b below
CAUTION! The PTO shaft is equipped
with shear bolt protection and this end of
the shaft MUST be fitted to the tractor PTO
shaft. (Pictograms stamped on PTO shaft
cover may be incorrect.)
4.1.8b Depress the two spring buttons and
slide onto the tractor shaft until the buttons
spring out into the correct locations.
4.1.9b Depress the single spring button on
the ratchet clutch end and slide onto the
chipper gearbox shaft until the button
