Disengaging Oilguard; Reversible Cutting Head - Husqvarna K 770 Operator's Manual

Disengaging OilGuard (K 770
OilGuard)
• When the machine is delivered, the OilGuard plug (A)
and the blue indicator pin (B) are fitted in the tank.
• If you are in a situation where you do not have access
to Husqvarna OilGuard oil, but you have oil of a similar
quality, you can deactivate the OilGuard system using
the disconnection function.
• To deactivate the function, pry off the OilGuard plug
using a screwdriver and then break off the indicator
pin. Now fit the disconnector plug (C) in the tank to
complete deactivation and to cover the hole.
• If you want to reactivate the OilGuard system, press
the OilGuard plug again. The system is then
reactivated, but note that the broken indicator pin
cannot be refitted.
• A broken indicator pin indicates that the OilGuard
system has been disconnected.
• You can purchase a new indicator pin as a spare, but
this is only sold in grey which indicates that the
OilGuard system has been deactivated since the
machine left the factory.

Reversible cutting head

The machine is fitted with a reversible cutting head
allowing cutting close to a wall or at ground level,
restricted only by the thickness of the blade guard.
In the event of a kickback it is harder to control the
machine when cutting with the cutting head reversed. The
cutting blade is further away for the centre of the machine
which means the handle and the cutting blade are no
longer in alignment. It is more difficult to restrain the
machine if the blade gets jammed or stuck in its kickback
danger zone. See under the "Kickback" heading in the
"Operating" section for additional information.
Some of the machine's good ergonomic features are
jeopardised such as balance. Cutting with the cutting
head reversed should only occur with cuts that are not
possible in a standard manner.
ASSEMBLING AND ADJUSTMENTS
• Loosen the three nuts (A) holding the upper belt
guard. Turn the belt tensioner (B) to position "0" to
release the tension.
• Remove the upper belt guard.
• Disconnect the water hose nipples and handle from
the blade guard (C). Remove the stop (D).
• The cutting head is now loose and can be removed
from the machine. Remove the belt from the belt
pulley.
• Rotate the bearing housing to opposite direction and
reassemble the stop.
