Dolmar ME-246.4 Original Instruction Manual page 19

Cleaning the chain-oil feed port
Clean the chain-oil feed port (A) daily. To access it, remove the bar holder and
guide bar.
Cleaning and inspecting the guide bar
Clean the guide bar daily. Remove saw dust from the groove (A) and chain-oil
feed port (B).
To avoid one side wear of the guide bar, turn it over every time you replace or
sharpen the saw chain.
If the groove is worn, bent, cracked or deformed, replace the guide bar.
Inspecting the saw chain
When you feel the saw chain is worn, deformed, cracked or you need more
effort for the cutting, replace it or ask Dolmar authorized service center to
sharpen it.
Lubricating moving parts
NOTICE: Follow the instruction of the frequency and amount of grease
supplied. Otherwise insufficient lubrication may damage moving parts.
Gear case:
Remove the grease plug (A) and fill lithium-base grease through the grease
hole (B) every 25 hours of operation.
Guide bar nose:
Apply grease (Shell Alvania No. 2 or equivalent) from the grease hole (C) every
10 hours of operation.
REPLACEMENT OF ENGINE OIL
Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of
replacement.
ATTENTION: In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil,
confirm that the engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of
scald.
Note: If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.
Interval of replacement: Initially, after 20 operating hours, and subsequently every 50 operating hours
Recommended oil: SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)
In replacement, perform the following procedure.
1) Confirm that the fuel tank cap (A) is tightened securely.
2) Place large container (pan, etc.) under drain hole (C).
3) Remove drain bolt (E) and then remove oil cap (B) to drain out oil from drain
hole.
At this time, be sure not to mislay drain bolt's gasket (D), or to make dirty
any of the removed components.
4) Once all the oil has been drained, combine gasket and drain bolt, and tightly
secure drain bolt, so that it will not loosen and cause leaks.
* Use cloth to fully wipe off any oil attached to bolt and equipment.
