PROCEDURE FOR USE Machine should only be used for cutting of hedges or growth materials up to a maximum diameter of 100mm. For safety purposes the machine is supplied with a blade protection guard that attaches over the knives of the cutterbar and is held in place with spring clips; the guard should be fitted to cutterbar at all times other than during work and must always be fitted during installation and transport.
START UP AND OPERATION Start up and operation of the cutterbar must only be carried out by an operator who has been fully trained in the use of such machinery and is fully aware of the dangers and hazards surround the use of this type of machine. Ensure all persons remain at a safe distance before starting the machine and at all times whilst it is running.
WORKING The work area should be thoroughly inspected prior to starting in order to detect and note possible dangers or hazards such as wire, steel poles or other foreign objects. All removable objects that could cause problems or danger should be cleared from the work area beforehand and any immovable objects or hazards clearly marked in order to avoid them.
OVERHEAD POWER LINES (OHPLs) It cannot be stressed enough the dangers involved when working in the vicinity of Overhead Power Lines (OHPLs). Some of our machines are capable of reach in excess of 8 metres (26’); they have the potential to well exceed, by possibly 3 metres (9’ 9”), the lowest legal minimum height of 5.2 metres from the ground for 11,000 and 33,000 volt power lines.

Definitions of Exclusion Zones Risk Assessment Before starting to work near OHPLs you should always assess the risks. The following points should be observed; Know the risks of contacting OHPLs and the risk of flashover. Find out the maximum height and maximum vertical reach of your machine. ...
MAINTENANCE Before any work is carried out on the machine it must be switched off and the hydraulic system freed of pressure. Remove the ignition key, and secure the carrier vehicle against unintended operation or movement. Always wear suitable protection such as gloves, safety glasses, safety boots etc. when carrying out maintenance or repair work on this machine.
Hydraulic Connections and Hoses Avoid twisting the fittings when replacing a hose. Always use two single-head wrenches to loosen and tighten hoses. Hoses will be impaired if they are twisted during installation and pressure pulses in twisted hoses can stress the steel mesh in the hose. The warranty on the hoses covers only the replacement of hoses due to defective materials or manufacturing defects.
