English
A depth gauge that is too low will increase the kickback
tendency of the pole pruner and can increase kickback
forces.
A depth gauge that is too high will prevent the cutter from
entering the workpiece and will lead to poor cutting
performance. Always keep the required distance between
depth gauge and cutting edge (a), @ 25.4.
To properly lower the depth gauge:
► Lay the appropriate file gauge for the chain pitch on the
chain and press it against the cutter to be checked. If the
depth gauge protrudes past the file gauge, the depth
gauge must be filed down.
► File the depth gauge so that it is flush with the top of the
file gauge.
► Afterwards, remove the file gauge and file the leading
edge of the depth gauge parallel to the service mark.
When doing this, be careful not to further lower the highest
point of the depth gauge.
► Lay the file gauge on the chain to check the height of the
file gauge. The highest point of the depth gauge must be
flush with the top of the file gauge.
► After sharpening, clean the chain thoroughly, removing
any filings or grinding dust.
► Oil the chain thoroughly.
