Sawing the trunk
Cross-cutting is sawing a felled tree into lengths. Make sure you always have a firm footing and good balance, with your feet apart when sawing. If possible
support the trunk and hold it up from the ground with branches, logs or wedges. Follow the instructions:
1. If the trunk is supported along its length it can be sawn from above (overcut).
2. If the trunk is supported in one end, it should be sawn in two steps. First cut one third of the diameter of the trunk from underneath (undercut) to prevent
splitting. Then saw from above (overcut) to meet the first cut and avoid the guide bar being clamped.
3. If the trunk is supported in both ends, it should be sawn in two steps. First cut one third of the diameter of the trunk from above (overcut) to prevent splitting.
Then saw from underneath (undercut) to meet the first cut and avoid the guide bar getting stuck.
4. Always stand uphill of the tree when cutting on slopes. (Img. 14)
5. Reduce the pressure on the guide bar towards the end of the cut, but keep a firm grip on the handles. This will give you better control over the sawing
when you break through.
6. Do not allow the chain to come into contact with the ground. Wait until the chain has stopped before moving to the next cut.
7. Release the power switch and allow the chain to stop before moving to the next tree.
• Be careful not to let the guide bar and the chain come into contact with the ground.
• Do not saw wood under tension. If the wood splits or if the guide bar is twisted there is risk of fatal and/or serious personal injury.
Limbing (Img. 15)
• Always stand on the opposite side of the trunk from the branch to be cut.
• Start from the root end, and work up.
• Always saw from underneath and up.
When limbing lying logs, cut the branches sticking up first. Branches bearing the weight of the trunk are cut after sawing up the log into pieces.
High branches or branches under tension can cause the chain to pinch.
MAINTENANCE
Switch off the chain saw, pull out the plug and wait until all moving parts have completely stopped and the saw has cooled before cleaning and/or performing
any maintenance tasks.
Do not carry out any other maintenance or adjustments than those described in these instructions. Maintenance and repairs not described in these instructions
should be carried out by an authorised service centre or other qualified personnel. Incorrect maintenance can result in the risk of personal injury and/or
material damage.
Cleaning the chain saw
1. Remove any debris.
2. Wipe the machine with a damp cloth.
Cleaning the guide bar lubrication slot
1. Remove the guide bar.
2. Clear the lubrication slot in the guide bar with a suitable tool.
3. Reinstall the guide bar.
Only clean the guide bar with plastic tools. Never use metal tools.
Checking chain lubrication
Do not use the chain saw without adequate lubrication of the chain, this will wear out the chain quicker.
1. Check the oil level in the tank.
2. Start the chain saw.
3. Run the chain when holding the guide bar about 15 cm over a suitable surface for 15 seconds. If the chain lubrication is working properly there should be
splashing of oil on the surface.
Sprocket lubrication
Wear heavy-duty safety gloves when handling the guide bar and chain.
Switch off the saw, pull out the plug and wait until all moving parts have completely stopped before lubricating it.
The guide bar sprocket should be lubricated at intervals of 25 working hours, or once a week during intensive use.
1. Clean the sprocket.
2. Press grease from the nozzle of the grease gun into the lubrication hole until it comes out by the edge of the guide bar. A grease gun with a slim nozzle
simplifies effective lubrication.
3. Pull the chain around the sprocket by hand. Repeat until the entire sprocket is lubricated.
