CAUTIONS
◯Before starting to saw, ensure that the saw blade has reached full speed revolution.
◯Should the saw blade be stopped or made an abnormal noise during operation, turn off the switch immediately.
◯When finished with a job, pull out the battery from the main body.
◯Twisting and forcibly pressing the saw during cutting can result in unreasonable pressure on the motor, so try to go straight quietly.
◯In the situation where the circular saw is continuously operated while replacing the battery with stocked spare batteries one after another, the motor tends to overheat. Therefore, whenever the housing becomes hot, give the saw a break for a while.
◯Avoid cutting operation in a state where the base bottom is afloat from the material being cut. Otherwise, the motor can get locked.
MOUNTING AND DISMOUNTING THE SAW BLADE
CAUTION
To avoid serious accident, ensure the switch is in the OFF position, and pull out the battery.
1. Dismounting the saw blade
(1)Set the cutting volume at maximum, and place the Circular Saw as shown in Fig. 19.
(2)Depress the lock lever, lock the spindle, and remove the
(3)While holding the safety cover lever to keep the safety cover fully retracted into the saw cover, remove the saw blade. (Fig. 20)
2.Mounting the Saw Blade:
CAUTION:
If the bolt is worked using other tools than the provided box wrench, excessive tightening and insufficient tightening may take place resulting in injury.
(1) Thoroughly remove any sawdust which has accumulated on the spindle, bolt and washers.
(2) As shown in Fig. 21, the side of Washer (A) with a projected center the same diameter as the inner diameter of the saw blade and the concave side of Washer (B) must be fitted to the saw blade sides.
*Washer (A) is supplied for 2 types of saw blades with the hole diameters of 16 mm and 30 mm. (When buying the Circular Saw, one type of washer (A) is spplied.)
In case the hole diameter of your saw blade does not correspond to that of washer (A), please contact the shop where you purchased the
Circular Saw.
(3)To assure proper rotation direction of the saw blade, the arrow direction on the saw blade must coincide with the arrow direction on the saw cover.
(4)Using the fingers, tighten the
CAUTION
After having attached the saw blade, reconfirm that the lock lever is firmly secured in the prescribed position.
REPLACING LIGHT BULB
CAUTION:
◯Make absolutely sure that the battery is removed from the main body before replacing the light bulb.
◯Immediately after the light is turned OFF, the bulb retains high temperature. Make sure to cool down the light bulb thoroughly before replacing it so as to prevent burns.
◯When replacing the light bulb, check the shape of
base as well as the rating (12 V, 5 W), and then carry out perfect mounting. Otherwise, the light bulb can come off and/or cause overheat.
1. Detaching light bulb
(1)Remove the convex part of the light cover from the concave part of the handle cover, and then pull out the light cover in the
(2)Push the back of the socket, and remove the socket and the light bulb together from the handle cover (Fig. 23).
(3)Remove the light bulb from the socket. (Fig. 24).
2.Attaching light bulb
Take procedures here that are contrary to the detaching procedures.
NOTE:
◯When attaching the light bulb to the socket, insert the light bulb until it lightly bumps against the socket.
◯When attaching the socket to the handle cover, align the socket with the hole of housing while watching the back of the socket shown in Fig. 24, and insert the socket until it lightly bumps against the handle cover.
MAINTENANCE AND INSPECTION
CAUTION:
Pull out battery before doing any inspection or maintenance.
1.Inspecting the saw blade:
Since use of a dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted.
CAUTION:
If a dull saw blade is used, reactive force is increased during cutting operation. Avoid the use of the dull saw blade without repair.
2.Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.
3.Maintenance of the motor
The motor unit winding is the very "heart" of the power tool.
Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
4.Inspecting the carbon brushes (Fig. 25)
The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensure that they slide freely whthin the brush holders.
