Indicator lamps
Lighted
Off
Blinking
E
• When only the lowermost indicator lamp (next to the
"E") blinks, or when none of the indicator lamps light,
the battery capacity has run out, so the tool does not
operate. In these cases, charge the battery or replace
the empty battery with a fully charged one.
• When two or more indicator lamps do not light even
after charging is complete, the battery has reached the
end of its service life.
• When the upper two and lower two indicator lamps light
alternately, the battery may have malfunctioned.
Contact your local DOLMAR authorized service center.
NOTE:
• The indicated capacity may be lower than the actual
level during use or immediately after using the tool.
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
ASSEMBLY
WARNING:
• Always be sure that the tool is switched off and
battery cartridge is removed before carrying out
any work on the tool. Failure to switch off and remove
the battery cartridge may result in serious personal
injury from accidental start-up.
• Never start the tool unless it is completely
assembled. Operation of the tool in a partially
assembled state may result in serious personal injury
from accidental start-up.
Installing the handle
For model AT-3623, AT-3624 (Fig. 16)
Loosen knob.
Place handle between handle clamp and handle holder.
Adjust the handle to an angle that provides a comfortable
working position and then secure by firmly hand-
tightening knob.
For model AT-3630, AT-3631 (Fig. 17)
Fit the barrier and grip onto the shaft pipe with four

located between the grip/barrier assembly and the
hanger.
Remaining capacity
70% to 100%
F
45% to 70%
20% to 45%
0% to 20%
Charge the battery.
The battery may have
malfunctioned.
Position the barrier on the left side of the tool. Then
tighten four screws so that the grip/barrier assembly
cannot move or rotate on the shaft pipe.
WARNING:
• Do not remove or shrink the spacer. The spacer
keeps a certain distance between both hands. Setting
the grip/barrier assembly close to the other grip beyond
the length of the spacer may cause loss of control and
serious personal injury.
Installing the guard (Fig. 18 & 19)
WARNING:
• Never use the tool without the guard illustrated in
place. Failure to do so can cause serious personal
injury.
In use of the metal blade (Fig. 20)
Fix the guard to the clamp with two bolts as shown.
Tighten the right and left bolts evenly.
In use of the nylon cutting head
CAUTION:
• While installing the guard extension be careful not
to contact the sharp nylon cord cutter provided on
the guard extension. Contact with the cutter could
result in personal injury.
Fix the guard to the clamp with two bolts as shown.
Tighten the right and left bolts evenly. (Fig. 21)
Mount the guard extension by placing it on to the
mounting track provided on the lower edge of the guard
and sliding it into position until the guard extension clicks
and locks into place. The extension guard is designed so
that it will only mount onto the guard in one direction.
NOTE:
• Remove tape adhered to cutter, which cuts nylon cord,
on guard extension at the first use. (Fig. 22)
To remove the guard extension, use a flat-blade
screwdriver and place it into the small notch provided on
the locking nub. To unlock the guard extension press
down on the locking nub while sliding the lower guard
extension in the direction indicated in the figure. Once the
guard extension starts to slide it is unlocked and can be
removed by continuing to slide it off of the guard.
Installing the cutter blade
WARNING:
• The outside diameter of the cutter blade must be
230 mm. Never use any blade exceeding 230 mm in
outside diameter.
CAUTION:
• The cutter blade must be well polished, free of cracks
or breakage. Polish or replace the cutter blade every
three hours of operation.
• Always wear gloves when handling the cutter blade.
• Always attach the blade cover when the tool is not in
use or is being transported.
• The cutter blade-fastening nut (with spring washer) is a
consumable part. If there appears any wear or
deformation on the spring washer, replace the nut. Ask
your local authorized service center to order it.
NOTICE:
• Be sure to use genuine Dolmar cutter blade.
