1.0 Introduction
Thank you for becoming the owner of this Redwood Global Ltd, Först TR6D wood
chipping machine. By observing the contents of this manual, we hope the chipper
gives safe and productive service. This user manual is intended for the
owner/operator to safely and effectively operate this chipper and carry out routine
maintenance between services. This is not a comprehensive service manual. See
Service Schedule for routine maintenance and when to take the chipper to a service
specialist. For engine maintenance, please refer to the engine manual supplied with
this chipper.
This chipper has been through a pre-delivery inspection before leaving the factory
and is ready to use.
Also, damage to property and this chipper may occur. Please observe and obey all
warning signs (decals) located on the chipper. Their meaning is covered in this
manual under decals.
All personnel working with this chipper must be adequately trained in its use and
most importantly, follow the advice on safe working practices.
Redwood Global Ltd endeavour to continuously develop and improve its products.
They reserve the right to make changes at any time, without notice or incurring any
obligation.
Continuous improvement will affect chipper design and production so there may be
minor discrepancies between the actual product and this manual.
This manual must remain with the chipper for reference by operators and includes
hiring or if the chipper is resold.
Before use and as a minimum, the safety and chipper operation
sections covered in Chapter 2 be read and understood. Failure to
do so could result in serious injury or loss of life to the operator
and others nearby.

2.0 Safety
2.1 Safety Working
Before using this chipper, make sure that you are trained and fluent in its operation.
Know the location of and how to use all the safety features. Know how to control the
feed and stop the chipper in an emergency. Be familiar with the hazards and safe
working practices to prevent injury and damage to property and chipper. Also be
aware of the legal restrictions for personnel and towing with vehicles.
•The minimum age for service personnel is 18
years. Personnel aged 16 can use the
chipper for training under supervision by a
suitably trained person of 18 years or over.
•Operators and personnel working with this
chipper must not be under the influence of
alcohol, drugs or medication that would impair
judgement, concentration or reaction times.
Excessive tiredness is also a risk.
•In use, woodchip and debris are ejected with
considerable force from the chute and can
travel up to 10m. Make sure the chute directs
woodchip to a safe location so that no one can
be harmed or property damaged. Do not allow
discharge to be directed onto roads or public
rights of way.
•Maintain a 10m exclusion zone around the
chipper and clearly mark if in a public area.
Keep this area free of material build up.
•Make sure the chipper is on even, level and
stable ground and cannot move or topple
when in use. Use wheel chocks if necessary.
•Keep children and animals well away from the
working area.
•The chipper operator must wear protective
equipment:
▪Chainsaw safety helmet (EN 397) with
mesh visor (EN 1731)
▪Correctly rated ear defenders (EN 352)
▪Work gloves with elasticated wrist bands.
▪Steel toe cap boots (EN345-1)
▪Close fitting heavy duty non-snag clothing.
Hi-viz clothing (EN 471) if needed.
▪Protect breathing with a face mask if
appropriate. Some plant material can give
off harmful dust and poisonous vapours.
This may cause respiratory problems or
serious poisoning. Check the material to
be processed before starting.
•DO NOT wear rings, bracelets, watches,
jewellery or anything that could be caught on
the material being fed and draw you into the
chipper.
•All personnel operating or feeding material into
the chipper must wear heavy duty non-snag
clothing to help prevent being caught on
material and drawn into the chipper. The feed
mechanism of this chipper uses high powered
hydraulic motors to drive sharp toothed rollers
that feed material into the cutting blades. DO
NOT take risks with it. NEVER ASSIST ANY
MATERIAL INTO THE FEED ROLLERS WITH
HANDS OR FEET. Use the wooden paddle or
further long material if necessary.
•Never climb onto the hopper area while the
chipper is in operation.
•CAUTION! –Keep hands and feet outside the
hopper. Do not attempt to force material into
the chipper by hand –use a piece of wood if
necessary.
•Material can be forcibly ejected from the hopper
towards the operator. Ensure full head and
face protection is worn.
•Very twisted material should be trimmed into
manageable pieces. Failure to do this can
result in material extending outside the hopper,
moving aggressively side-to-side creating a
hazard to the operator.
•Do not try to force material over 150mm in
diameter into the chipper.
•Carefully site the chipper so operators can work
furthest from any local danger. For example,
on a road side, place chipper so operators work
on the verge and not in the road exposed to
traffic

2.2 DO’s and DON’Ts
•DO ensure that the starting of the chipper can cause
no hazard before starting. i.e. no persons are in the
hopper or in any other danger aera
•DO stop the chipper before making any adjustments,
refuelling or cleaning
•DO make sure the chipper has stopped rotating and
remove the ignition key before any maintenance or the
chipper is left unattended. The belts and pulley are to
be used to ensure visually that the chipper has
stopped rotating
•DO ensure that the chipper is level, well supported
and cannot move during use
•DO run the chipper at full throttle
•DO conduct regular chipper checks for visual fluid
leaks
•DO take regular breaks. Wearing protective
equipment can be hot and tiring leading to a lack of
concentration, increasing the risk of having an
accident
•DO keep hands, feet and clothing out of feed area,
chute and moving parts
•DO always check the all of controls and safety devices
(emergency stops, stop bar) before feeding any wood
into the chipper
•DO remove any additional debris attached to the wood
before commencing work i.e. nails, wire, rope etc
•DO NOT use chipper in poor visibility or insufficient
light to see clearly
•DO NOT use or attempt to start the chipper without the
discharge chute or guards correctly and securely fitted
•DO NOT stand directly in front of the in-feed hopper
when using the chipper. Stand to one side
•DO NOT allow the following to enter the chipper as
damage is likely:
•DO NOT stand in front of the chute
•DO NOT smoke when refuelling. Petrol fuel is highly
flammable and explosive in certain conditions
•DO NOT let anyone who has not received instruction,
operate the chipper
•DO NOT climb on the chipper at any time except for a
tracked chipper ride-on plate where fitted
•DO NOT handle material partially engaged in the
chipper while in operation
•DO NOT touch any exposed wiring whilst the chipper
is running
•DO NOT restart the chipper immediately if an
emergency stop has caused a shut down. Before
disengaging the emergency stop a thorough
inspection of the chipper should be carried out to
ensure the safety conditions are being met
