13 Lubricating the Gearbox
If the overload cutout has disconnected the
power:
► Remove the trimmer blades from the cut
► Wait for approx. 3 minutes until the overload
cutout has cooled down
Do not switch on the machine during this time,
because this substantially extends the cooling
down period.
Once the machine starts again:
► Let the machine run for approx. 15 seconds
without load – this cools the windings of the
motor and substantially delays renewed trig‐
gering of the overload cutout
13 Lubricating the Gearbox
13.1
Blade drive
For the blade drive, use STIHL gear lubricant for
hedge trimmers (special accessory).
► Check lubricant filling periodically and after
approx. every 25 hours of operation
► Unscrew the locking screw (1) – if no lubricant
is visible on the inside of it, then screw in the
lubricant tube
► Squeeze up to 5 g of lubricant into the gear
unit
NOTICE
Do not completely fill the gear unit with lubricant.
► Unscrew lubricant tube
► Refit locking screw (1) and tighten securely
13.2
Angle drive
For the angle drive, use STIHL gear lubricant for
hedge trimmers (special accessory).
0458-277-9821-B
► Check lubricant filling periodically and after
approx. every 25 hours of operation
► Unscrew the locking screw (2) – if no lubricant
is visible on the inside of it, then screw in the
lubricant tube
► Squeeze up to 5 g of lubricant into the gear
unit
NOTICE
Do not completely fill the gear unit with lubricant.
► Unscrew lubricant tube
► Refit locking screw (2) and tighten securely
14 Storing the Machine
If not used for periods of about 30 days or longer
► Clean cutting blades, check condition and
spray with STIHL resin solvent
► Attach blade scabbard
► Thoroughly clean the machine, especially the
ventilation slots
► Using the built-in ring on the bottom of the
motor housing, store the machine in a dry,
secure place. Keep out of the reach of children
and other unauthorized persons
15 Sharpening Instructions
When cutting performance and behavior begin to
deteriorate, i.e. blades frequently snag on
branches: Resharpen the cutting blades.
It is best to have the cutting blades resharpened
by a dealer on a workshop sharpener. STIHL
recommends a STIHL servicing dealer.
It is also possible to use a flat crosscut sharpen‐
ing file. Hold the sharpening file at the prescribed
angle (see "Specifications").
► Only sharpen the cutting edge – do not file
blunt projecting parts of the cutting blade or
the cutting blade guard (see "Main Parts and
Controls")
► Always file towards the cutting edge.
► The file only sharpens on the forward stroke –
lift it off the blade on the backstroke.
