15 minutes before proceeding with a fresh battery.

Drilling in wood

When drilling in wood, the best results are obtained with

wood drills equipped with a guide screw. The guide

screw makes drilling easier by pulling the bit into the

workpiece.

Drilling in metal

To prevent the bit from slipping when starting a hole,

make an indentation with a center-punch and hammer at

the point to be drilled. Place the point of the bit in the

indentation and start drilling.

Use a cutting lubricant when drilling metals. The

exceptions are iron and brass which should be drilled dry.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and the

•

battery cartridge is removed before attempting to

perform inspection or maintenance.

Never use gasoline, benzine, thinner, alcohol or the

•

like. Discoloration, deformation or cracks may

result.

To maintain product SAFETY and RELIABILITY, repairs,

any other maintenance or adjustment should be

performed by Makita Authorized Service Centers, always

using Makita replacement parts.
