Remove the sprocket cover and saw chain from the tool.
(Refer to the section titled “Installing or removing saw
chain”.)
Remove the push nut using a slotted bit screwdriver with
a slender shaft or the like. (Fig. 37)
Take the filter out of the chain saw and remove small dust
or particles from it.
When the filter is too dirty, replace it with a new one.
Plug in the tool. (Fig. 38)
Pull the switch trigger to flow built-up dust or particles off
the oil discharge hole by discharging chain oil.
Unplug the tool from the mains. (Fig. 39)
Insert the cleaned oil filter into the oil discharge hole.
When the filter is too dirty, replace it with a new one.
(Fig. 40)
Insert the push nut with its correct side facing up as
shown in the figure into the oil discharge hole to secure
the filter. When the filter cannot be secured with a disfig-
ured push nut, replace the push nut with a new one.
- Reinstall the sprocket cover and saw chain on the tool.
(Fig. 41)
New saw chains
Use two or three saw chains alternately, so that the saw
chain, sprocket and running surfaces of the bar wear
evenly.
Turn the bar over when changing the chain so that the bar
groove wears evenly.
CAUTION:
• Only use chains and bars which are approved for this
model of saw (refer to “SPECIFICATIONS”). (Fig. 42)
Before fitting a new saw chain, check the condition of the
sprocket.
CAUTION:
• A worn sprocket will damage a new saw chain. Have
the sprocket replaced in this case.
Always fit a new locking ring when replacing the sprocket.
Maintaining the chain and run-down
brakes
The braking systems are very important safety features.
Like any other component of the chain saw, they are sub-
ject to a certain degree of wear. They must be inspected
regularly by a MAKITA specialist repair shop. This mea-
sure is for your own safety.
Storing tool
Biologically degradable saw chain oil can only be kept for
a limited period.
Beyond two years after manufacture, biological oils begin
to acquire an adhesive quality, and cause damage to the
oil pump and components in the lubricating system.
- Before taking the chain saw out of service for a longer
period, empty the oil tank and fill it with a small quantity
of engine oil (SAE 30).
- Run the chain saw briefly to flush all residue of the bio-
logical oil out of the tank, lubricating system and saw
mechanism.
When the chain saw is taken out of service, small
quantities of chain oil will leak from it for some time
afterwards. This is normal, and is not a sign of a fault.
Store the chain saw on a suitable surface.
Before returning the chain saw to service, fill up with fresh
BIOTOP saw chain oil.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
