WORKING TECHNIQUES General working instructions suddenly. Take great care when working on sloping ground. Take great care when cutting a tree that is in tension. IMPORTANT! A tree that is in tension may spring back to its normal This section describes basic safety rules for using a position before or after being cut.
WORKING TECHNIQUES • Work systematically to and fro across the area, When cutting, work in the 9 to 12 o' clock sector. clearing a width of around 4-5 m on each pass. This exploits the full reach of the machine in both directions and gives the operator a convenient and varied working area to work in.
WORKING TECHNIQUES • Whenever possible position yourself so that you can tearing of the bark, which could lead to slow healing make the cut at right angles to the branch. and cause permanent damage to the tree. The cut should not be deeper than 1/3 of the branch thickness to prevent jamming.

MAINTENANCE Loosen the two screws (A) and (B), and remove the cutting head from the shaft. Check that there is grease in the gear housing by looking in the hole for the drive shaft (se picture). If no grease can be seen, the gear housing should be ﬁlled with new grease.
Check and clean the spark arrestor mesh on the mufﬂer (only applies to mufﬂers ﬁtted with a catalytic converter). Lubricate the drive axle with Husqvarna drive axle grease. Do this every six months. Check that there is grease in the gear housing. If necessary, ﬁll Do this every six months.
