4. Tighten the lock lever (A) firmly as shown.
To remove the attachment, loosen the lock lever, press the lock
button and withdraw the shaft.
NOTICE: Do not tighten the lock lever (A) without the shaft of the
attachment inserted. Otherwise the lock lever may tighten the
entrance of the drive shaft too much and damage it.
Assembling saw chain and guide bar (Fig. 7 & 8)
Caution: Make sure that the saw chain, guide bar and sprocket
match each other in gauge and pitch.
Assemble the saw chain and guide bar as the following steps.
1. Loosen the nut (A) and remove the bar holder (B).
2. Fit the saw chain (C) into the groove of guide bar (D). Start at
the bar nose.
3. Fit the saw chain (C) onto the sprocket (E).
4. Install the guide bar (D) so that the tensioning nut (F) fits into the
hole on the guide bar.
5. Fit the bar holder (B) and tighten the nut (A) securely. Then
loose the nut a half turn as a provision of the chain tension
adjustment.
6. Adjust the chain tension. Refer to the section "Adjusting the
chain tension."
Adjusting the chain tension
WARNING:
• Before check or adjust the chain tension, switch off the motor and
remove the spark plug cap or the battery cartridge.
• Before check or adjust the chain tension, wear protective gloves.
Caution:
• Keep the applicable chain tension. Loose tension can cause the
saw chain to come off during operation. Too tight tension can
damage the saw chain or guide bar.
• During operation, check the chain tension frequently. The saw
chain stretches and becomes loose during operation. When use
a new saw chain, adjust the tension more frequently. (Fig. 9)
Adjust the chain tension as the following steps.
1. Loose the nut (A) a half turn.
2. Hold the bar nose up. Turn the tensioning screw (B) clockwise
until the saw chain fits the underside of the guide bar snugly.
3. Pull the saw chain along the guide bar by hand. If it is hard to
move, turn the tensioning screw counterclockwise slightly and do
the step 2 again.
4. Tighten the nut (A) securely.
Filling the chain oil tank
The saw chain must be lubricated with chain oil during operation.
Before operation, fill the chain oil tank. After supplying the oil,
tighten the oil cap securely.
The recommended chain oil is:
SAE10W-30,
SAE#30 to #40 in Summer or
SAE#20 in Winter.
Notice: Never use waste oil. It may damage the oil pump.
During operation, always pay attention to the oil level. Refill the
tank if the oil level becomes low. The tank becomes empty in
approximately 40 minutes of operation (depending on the setting of
the chain lubrication).
Adjusting the chain-oil feeding rate (Fig. 10 & 11)
The chain-oil feeding rate is adjustable in three steps. It is factory
set to the low feeding rate. According to the operation, for example
cutting hard limbs, increase the feeding rate.
To adjust the chain-oil feeding rate, use a flat-bladed screwdriver.
Push in the adjusting screw and turn it to the desired feeding rate
position.
A: Low
B: Medium
C: High
After adjusting the chain-oil feeding rate, check the feeding rate by
driving the equipment at medium speed.

Inspection and maintenance

WARNING:
• Before inspecting or maintaining the equipment, switch off the
motor and remove the spark plug cap or the battery cartridge.
Otherwise saw chain or other parts may move and result in
serious injury.
• Before handling or working around saw chain, wear protective
gloves. Otherwise the saw chain can cut bare hands severely.
• When inspecting or maintaining the equipment, always put it
down. Assembling or adjusting the equipment in an upright
position may result in serious injury.
• Follow the warnings and precautions in the chapter "Safety
precautions" and the instruction manual of the power unit.
Cleaning the chain-oil feed port (Fig. 12)
Clean the chain-oil feed port (A) daily. To access it, remove the bar
holder and guide bar.
Cleaning and inspecting the guide bar (Fig. 13)
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 or deformed, replace the guide bar.
Inspecting sprocket (Fig. 14)
Check the sprocket for wear every 50 hours of use. Replace it if the
wear marks becomes 0.3 mm or deeper.
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 (Fig. 15)
NOTICE: Follow the instruction of the frequency and amount of
grease supplied. Otherwise insufficient lubrication may damage
moving parts.
Gear case:
Fill lithium-base grease through the grease nipple (A) every
25 hours of operation.
Drive axle:
Apply grease (Shell Alvania No. 2 or equivalent) every 25 hours of
operation.
Guide bar nose:
Apply grease (Shell Alvania No. 2 or equivalent) from the grease
hole (B) every 10 hours of operation.
Overall inspection
• Tighten loose bolts, nuts and screws.
• Check for damaged parts. Ask Dolmar authorized service center
to replace them.

Storage

WARNING: Follow the warnings and precautions in the chapter
"Safety precautions" and the instruction manual of the power unit.
(Fig. 16)
When storing the pole saw attachment separated from the power
unit, put the cap onto the end of the shaft.
