Checking chain lubrication
Bvqr7h
The nose and underside of the guide bar are subject to a
particularly high rate of wear. To avoid one-sided wear, turn
the bar over every time youresharpen or preplace thechain.
Regular cleaning of the oil inlet holes and guide bar groove
is also important. The bar can be examined for signs of wear
at the same time.
A minimum bar groove depth must be maintained in order
to prevent the drive links contacting the bottom of the groove
(the heels of the cutter and tie strap would no longer on the
guide bar rails). The groove depth varies according to chain
type and pitch:

Chain type

Chain pitch
3/8 "
Minumum depth
5 mm (0.2")
Every new chain has to be broken in forabout2to 3minutes.
Ample chain lubrication is essential during this period. After
breaking in, stop the engine, check chain tension and adjust
if necessary.
The groove depth should be measured at the point where
the bar is stressed most. That is the bar nose on Duromatic
bars and the area where most of the cutting is done in
Rollomatic bars. The guide bar must be replaced when
groove depth is less than the specified minimum.

Never operate the chain saw without proper chain lubrica-
tion. If the chain is allowed to run dry the whole cutting
attachment will be irretrievably damaged within a very short
time. For this reason you should always check operation of
the chain lubrication system and the level in the oil tank
before starting work.
On Rollomatic guide bars it is not necessary to separately
lubricate the sprocket nose bearing because the chain oil
which flows to the bearing by way of the bar groove during
normal operation is adequate for lubrication.
Start the saw and hold the cutting attachment over a light
patch of ground. Take care – the Oilomatic chain must not
touch the ground; hold it at least 20 cm (8 in) clear of the
ground. Run theengineatabouthalfthrottle.Ifanincreasing
film of oil can be seen on the ground, chain lubrication is
operating correctly. If this is not the case, refer to "Trouble-
shooting on Chain Oiling System".
