FUNCTIONAL DESCRIPTION • 001661 1 3 2 Installing or removing battery cartridge • Always switch off the tool before insertion or removal of the battery cartridge. • To remove the battery cartridge, withdraw it from the tool while sliding the button on the side of the cartridge. • To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click.
5. If you leave the battery cartridge in the charger after the charging cycle is complete, the charger will switch into its “trickle charge (maintenance charge)” mode which will last approximately 24 hours. 6. After charging, unplug the charger from the power source. NOTE: • The battery charger is for charging Makita battery cartridge. Never use it for other purposes or for other manufacturer’s batteries.
• Check the sound of cooling fan, vent on the charger and battery, which can be sometime clogged with dust. • The cooling system is in order although no sound of cooling fan comes out, if the yellow warning light will not flash. • Always keep clean the vent on charger and battery for cooling. • The products should be sent to repair or maintenance, if the yellow warning light will frequently flash.
001663 1 Adjusting shoe When the blade loses its cutting efficiency in one place along its cutting edge, reposition the shoe to utilize a sharp, unused portion of its cutting edge. This will help to lengthen the life of the blade. To reposition the shoe, loosen the lever counterclockwise and slide the shoe forward or back to the desired position. Then tighten the lever clockwise to firmly secure the shoe. 2 1. Lever 2.
ASSEMBLY • CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Installing or removing the saw blade • 001666 To install the saw blade, always make sure that the blade clamp sleeve is in released position before inserting the saw blade. If the blade clamp sleeve is in fixed position, rotate the sleeve to the released position. 001667 Insert the saw blade into the blade clamp as far as it will go.
OPERATION 001669 • CAUTION: Always press the shoe firmly against the workpiece during operation. If the shoe is held away from the workpiece during operation, strong vibration and/or twisting will be produced, causing the blade to snap dangerously. • Always wear gloves to protect your hands from hot flying chips when cutting metal. • Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause premature blade wear.

Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.
