• Never travel across a STEEP slope or side hill. • Always carry any load on the uphill side of the machine. • Do not lift or move objects that exceed machine stability. • Always be prepared to release the load in case it causes the machine to tip. • Always position the cab so that you have a clear view in the direction of travel. Be aware of ground conditions and obstacles in the machine’s path before moving the machine. • When crossing obstacles (boulders, stumps, ditches etc.) the machine can shift rapidly, greatly affecting the stability of the machine.
Move slowly over obstacles, and position the boom against the ground to reduce the risk of the machine shifting rapidly. • Backing over obstacles unexpectedly while traveling down a slope poses a tipping risk.
Know the path of the tracks whenever the machine is moved. • When climbing a slope the boom should face uphill and the attachment should be kept close to the ground (FIG. 3). When descending a slope the boom should face down hill and the attachment should be kept close to the ground (FIG.4). Be aware that the machine is in its least stable position on a slope with the boom to the rear (see also
FIG.1). Be particularly aware of machine stability when changing directions on, or travelling back down a slope. • As you gain experience, recognize that the maximum slope on which the machine can operate cannot be defined simply by an angle value. Variables in surface terrain, soil types, rocks, boulders, stumps, and fallen trees, changing weather conditions, and first and foremost the operator’s experience and skill levels greatly affect the maximum slope limitations. Be aware that these factors can result in a shallow slope posing greater risk than a relatively steeper slope. DO NOT
attempt to work on slopes beyond your personal capability level.

HARVESTING ATTACHMENT – GENERAL SAFETY:
Improper operation, maintenance or repair of this product can be dangerous and could result in injury or death. Do not operate or perform any maintenance or repair of this product until you have read and understood the operation and repair information contained in the manuals provided by the attachment manufacturer. The following are general safety guidelines for harvesting attachments. Note the design, operation, and maintenance of attachments varies among manufacturers. Always follow the specific safety, maintenance, and operating procedures provided by the attachment manufacturer. The operator of the carrier and harvesting head must be properly trained in the operation of the equipment and its safety requirements.
PRIOR TO STARTING OPERATION:
• Ensure no one is near the machine where the risk of personal injury is present. • Ensure no one is in the line of the chain saw when starting or operating the harvesting head. The hydraulically driven saw chain reaches high speeds and is an extreme hazard if the chain breaks.
• Regularly inspect, check and maintain the saw guide (bar), the saw chain and sprocket, ensuring that all components are secure and not damaged as detailed in the harvesting attachment operator’s manual. • Ensure that all safety equipment upgrades available from the attachment manufacturer have been installed.
• Before starting each shift the operator must test ALL functions of the carrier and attachment to ensure that they are in proper working order.
OPERATION:
Felling trees with the harvester is very dangerous and should be done only by properly trained and experienced operators.
• Lower attachment to ground and turn pilot system off whenever machine is not in use. • Always fell trees in the direction that they are leaning. • Never fell trees close to overhead power lines, vehicles, houses, roads/pathways, etc. • Never fell trees when there are personnel on the ground within the 150 metre (500 ft)
“hazard zone.”
• During operation do not allow anyone within the safety zone of at least 150 metres (500 ft) from the machine.
• Never fell trees in the direction of the operator’s cab.
WARNING
The attachment may release held trees when the cab front door is opened, the pilot system is turned off or the fire suppression system is activated. Never exit the cab with a tree suspended in the attachment. WARNING
The operator must release trees from the attachment, place attachment on the ground, and shut pilot system off if someone enters into the hazard zone.

OPERATING SAFETY PRECAUTIONS continued
WARNING
Avoid the risk of chain shot. Never operate the attachment so that the saw bar is directly in line with the cab or any personnel!
• Do not process trees with the saw guide (bar) aligned with the operator’s cab. The hydraulically driven saw chain reaches high speeds and is an extreme hazard if the chain breaks. • Operate so that the chip discharge area of the harvesting head is not directed at people, livestock, houses, buildings, roads or other machines. • Be particularly observant with the zone in line with the chain saw.
SERVICING AND REPAIR:
Before beginning any service work on the harvesting head, place the machine on level ground, place the attachment on the ground and properly support the boom, refer to PARKING BOOM Figure 5.
Stop the machine engine and turn the battery disconnect switch to the OFF position. Install any safety chains or locking parts required by the attachment manufacturer. Ensure that any accumulators on the attachment are completely relieved of hydraulic pressure. Always follow the specific safety, maintenance, and operating procedures provided by the attachment manufacturer.
• Never place any part of your body between the roll arms or delimbing arms. This area is a crush zone. Keep clear to avoid personal injury or death. • Never place any part of your body near the rolls. Avoid the risk of entanglement in moving parts. Keep clear to avoid personal injury or death. • Never place any part of your body in front of the saw guide (bar). Avoid the risk of dismemberment. Keep clear to avoid personal injury or death. • When working in the area of the roll arms, delimbing arms, or rolls and when changing the saw guide (bar) or saw chain the machine must be completely shut down, with the battery disconnect switch to the OFF position. • Do not change the pressure settings of any hydraulic valves or make structural modifications to the harvesting head without obtaining authorized instructions from the attachment manufacturer.
