(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become hot
should be cooled for a while before being recharged.
Table 2 Recharging ranges of batteries
Rechargeable batteries
BSL3620
(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

NOTE
The charging time may vary according to temperature
and power source voltage.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
After operation, pull out batteries from the charger fi rst,
and then keep the batteries properly.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a while.
CAUTION
○ If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used, the
pilot lamp of the charger lights up green. In such a case,
fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects in
the charger's battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○ Since the built-in micro computer takes about 3
seconds to confi rm that the battery being charged
with UC36YRSL is taken out, wait for a minimum of 3
seconds before reinserting it to continue charging. If
the battery is reinserted within 3 seconds, the battery
may not be properly charged.

INSTALLING (REPLACING) SAW CHAIN

WARNING
○ To prevent accidents, always switch the unit off , and
remove the storage battery.
○ Don't use the saw chain or the guide bar other than
those specifi ed in "SPECIFICATIONS".
CAUTION
Wear gloves and be careful to avoid injury with the saw
chain.
NOTE
○ When removing the saw chain, remove sawdust from
the oil spout, oil hole, and guide bar groove.
If sawdust accumulates, this may cause the unit to fail.
○ Use the correct type of saw chain in accordance with
the specifi cations.
If you install the wrong type of guide bar, the saw chain
may come off and injury may occur.
1. Removing the side cover (Fig. 6)
1 Rotate the knob once to loosen it.
2 Rotate the tension dial half a turn to loosen it.
3 Using the supplied hexagonal bar wrench, loosen the
bolt until there is no resistance.
4 Turn the knob and remove the side cover.
2. Removing the saw chain and guide bar (Fig. 7)
Remove the saw chain and guide bar in the direction
indicated by the arrow.
3. Engaging the new saw chain in the sprocket (Fig.
8, 9)
Engage the saw chain at the guide bar tip with attention
to the direction of the saw chain, and then properly
engage the saw chain with the sprocket.
4. Installing the side cover
1 Align the bolt with the bolt hole (Fig. 10)
2 Adjust the tension dial of the side cover so that the
chain tensioner boss is inserted into the guide bar chain
tensioner hole, and attach the side cover. (Fig. 11)
3 Rotate the knob once to temporarily fi x it. (Fig. 12)
5. Adjusting the saw chain tension (Fig. 13)
○ While lifting the guide bar tip, turn the tension dial to
adjust the saw chain tension.
○ Turn the tension dial to the right to increase the saw
chain tension, and to the left to decrease it.
6. Checking the saw chain tension (Fig. 14)
Adjust the saw chain tension so that the gap between
the saw chain drive link and the guide bar is 0.5 to 1 mm
when you lift the saw chain slightly near the center of
the guide bar.
7. Securing the knob (Fig. 15)
1 When adjustment is complete, lift up the guide bar, and
fully tighten the knob.
2 Make sure the bolt is fi rmly tightened.
WARNING
After adjusting the saw chain tension, ensure the knob
is fully tightened.
If it is loose, injury may occur.
