D. ASSEMBLY / DISASSEMBLY
BAR AND CHAIN ASSEMBLY
Take great care when assembling to ensure this is performed correctly.
Remove the plug from the power supply before working on the product.
1a & 1b. Check that the chain brake is not activated. If so, deactivate it.
2a & 2b. Unscrew the chain tensioning knob and rotate in an
Wear Gloves.
3 Position the chain over the bar, starting at the nose sprocket, fitting it into the guide bar groove.
Ensure that the sharp side of the cutting teeth face in a forward direction on the upper part of the bar.(see markings on the bar)
4. Rotate the chain tensioning mechanism
5a & 5b. Mount the bar on the bar retaining screw and it will attach to the magnet. Position the chain over the drive sprocket.
6a & 6b. Replace the drive sprocket cover, ensuring the drive teeth of the chain are engaged in the drive sprocket and in the bar guide groove.
7a & b. To tension the chain, turn the chain tensioner knob in a clockwise direction until securely tightened. The chain is now tensioned correctly for use.
Tensioning the chain too tightly will overload the motor and cause damage. Insufficient tension can provoke chain derailing, whereas a chain tightened correctly provides the best cutting characteristics and prolonged work life. Check the tension regularly because the chain length tends to stretch with use (especially when the chain is new; after the first assembly, the chain tension must be checked after a few minutes machine operation); in any case do not tighten the chain immediately after use, but wait until it cools down.
In cases where the loosened chain needs to be adjusted, always unscrew the chain tensioning knob 2 turns and then securely tighten again leaving the chain tensioned for use.
Warning:- The chain and guide bar can become very hot
E. START-UP AND STOPPING
Stopping: The machine will stop whenever the switch is released or by activating the chain brake.
F. BAR AND CHAIN LUBRICATION
ATTENTION! Insufficient lubrication will provoke chain breaking and can cause serious injury.
Refer to “Maintenance & Storage” for indications on ensuring that the chain oil is sufficiently distributed.
Choice of chain oil
Use oil which is approved by the manufacturer.
We advise the use of bio chain oil which is biologically degradable.
Filling oil tank
Unscrew the oil tank cap, and fill the tank taking care not to spill any oil (if this occurs clean the machine carefully) and then screw the cap back on tightly.
