GM C/S100 1. INTRODUCTION AND PURPOSE 1-1

INTRODUCTION

This manual explains the proper operation of your machine. Read these instructions thoroughly before operating and maintaining the machine. Failure to do so could result in personal injury or equipment damage. Consult your GreenMech supplier if you do not understand the instructions in this manual.

CAUTION! This symbol indicates important safety messages in this manual. When you see this symbol, be alert to the possibility of injury to yourself or others, and carefully read the message that follows.

We recommend that you keep this manual with the machine in the box provided. Note here the serial number and quote it in any communications. This is important when ordering spares. Remember to include all numbers and letters.

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 operators who are familiar with the content of this instruction manual. It is potentially hazardous to fit or use any parts other than genuine GreenMech parts. The company disclaims all liability for the consequences of such use,

which in addition voids the machine warranty.

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.

Full details are included in the Risk Assessment in the Appendix.

CAUTION! Operators must wear appropriate ear protection. Bystanders must be

kept away from proximity of machine.

Safety Guides and Checklist as

Transcribed from and Advised by

Arborculture & Forestry Advisory Group

and Issued as Leaflet 604 by HSE, issued

04/03

INTRODUCTION

This leaflet covers the safe working practices to be followed when operating a wood chipper.

It does not cover a combination of machines working within each other’s risk zones (see AFAG leaflet 605 Mechanical roadside

processing)

You can use this leaflet, along with the manufacturer’s handbook, as part of the risk assessment process to help identify the controls to put in place when using a wood chipper.

You must also assess the effect of the site and the weather as well as following this guidance

All operators must have had appropriate training in how to operate the machine and how to carry out the tasks require (see AFAG leaflet 805 Training and certification)

PERSONAL PROTECTIVE

EQUIPMENT (PPE)

1. Use the following PPE

•

A Safety Helmet, complying with EN 397, if identified as required in the risk assessment.

Eye Protection (a mesh visor complying with EN1731 or safety glasses to EN166)

Hearing protection (complying with EN352) where noise level exceeds 85 dB(A) (see HSE pocket card INDG363

Protect your hearing or lose it!)

Gloves.

Safety Boots with good grip and ankle

support (complying with EN345-1)

Non-Snag Outer Clothing appropriate to prevailing weather conditions. Highvisibility clothing (complying with EN471) should be worn when the risk assessment identifies that it is needed.

2. Each person should carry a personal first-

aid kit including a large wound dressing (see HSE leaflet INDG214 first aid at

work; Your questions answered).

3. Hand cleaning material such as waterless

skin cleanser or soap, water and paper towel should be readily available.

THE MACHINE

4. Before working with a machine, check it

has been properly converted from any transport mode.

5. Ensure guards for dangerous parts (e.g.

belts, pulleys, shafts etc) are secure and undamaged.

6. Ensure protective devices, such as the

infeed control bar (incorporating the stopping device), are working correctly (see HSE leaflet AI S 38 Power-fed

mobile wood chippers: Operator protection at infeed chutes).

7. Ensure any lock for the chipping

components has been disengaged;

8. Ensure the infeed hopper is clear of any

materials.

9. Ensure Noise warning signs are in place.

10. For machines driven by a power take-off

(PTO) shaft, before starting ensure:

Page 1

•

The PTO shaft is fitted with a suitable guard complying with EN1152, that encloses the shaft along its full length from tractor to machine.

The guard is correctly fitted and in effective working order (see AS24(rev)

Power take-offs and power take-off drive shafts);

The PTO speed is suitable for the machine.

SELECTING THE WORK AREA

11. Select as firm a surface as possible and

stabilise the machine

12. Ensure ventilation is adequate and any

exhaust fumes are vented into open air if working in an enclosed space.

13. Where appropriate, if the chipper is

detached from the tow vehicle, apply the handbrake and, if necessary, chock the wheels.

14. On all reasonably foreseeable approaches

to the worksite, erect warning and prohibition signs conforming to the Health and Safety (Safety Signs and Signals) Regulations 1996, indicating a hazardous worksite and that unauthorised access is prohibited. In areas of very high public access, a risk assessment may indicate that additional controls (e.g. barrier tape, barriers, extra manning) are required.

15. Ensure all operations near to highways are

adequately signed with the appropriate notices as specified in the DTLR Code of Practice Safety at street works and road works (available from The Stationary Office ISBN 0 11 551958 -0)

16. Ensure that the discharge chute is

positioned to prevent chips being blown onto the highway during roadside operations, or in any direction where they

can affect colleagues or members of the public.

17. Position the chipper so that operators do

not have to stand on embankments/slopes when feeding material into the machine

EMERGENCY PROCEDURES

18. Ensure a designated and responsible

person knows the daily work programme and agree with them a suitable emergency contact procedure. Where reasonably practicable use a mobile phone or radio and pre-arrange call-in system.

19. Ensure the operators can provide the

emergency services with enough detail for them to be found in the event of an accident, e.g. the grid reference, the distance from the main road, the type of access (suitable for car/four-wheel drive/emergency service vehicles). In urban areas street names are essential. Know the location details before they are needed in an emergency. (Also see AFAG leaflet 802 Emergency planning)

OPERATION

20. Make sure the cuffs of gloves are close

fitting or tucked into you’re sleeves to stop them being caught on material as it is fed into the chipper.

21. Set the engine speed (and set the stress

control if fitted) to obtain optimum performance.

22. Check that material to be chipped is free

from stones, metal and foreign objects.

23.

Stand to one side of the infeed rollers to

avoid being hit by ejected material.

24. Let material go as soon as it is engaged in

the infeed rollers or chipping components.

Page 2

25. Use a push stick at least 1.5 metre long,

for both short produce and for the last piece of produce to be chipped.

26. Do not put any part of your body

(including hands or feet), into the infeed hopper while the machine is running.

27. Always follow the manufactures’

instructions for dealing with blockages on the machine.

28. Keep the area of ground in front of the

infeed hopper free from debris to prevent any tripping hazard.

29. Remove the engine start key when the

machine is left unattended or when undertaking any maintenance.

FUELLING

30. Stop engine and, if necessary allow the

machine to cool before refuelling.

31. Petrol vapour is invisible and can flow

considerable distances from spillage or fuelling sites. Maintain a safe distance from any source of ignition at all times.

32. Store fuel to avoid vapour ignition from

any source such as fires, people smoking or the wood chipper. Select a site shaded from direct sunlight and away from watercourses and drains.

33. Containers must be clearly labelled and

have securely fitting caps. Plastic containers must be designed and approved for use with petrol or diesel fuel.
