GEAR SHIFTING
Your tool is equipped with two separate gear ranges, Hi-torque “1”and High speed “2” (see fig.5).
Hi-torque provides high-torque and slower drilling speeds for heavy duty work or for driving screws.
High-speed provides faster speeds for drilling lighter work. To change speeds slide switch, to the
Hi-torque or High-speed position.
WARRNING: Always set the speed change lever fully to the
correct position. If you operate the tool with the speed change
lever positioned halfway between the "1" side and "2" side, the
tool may be damaged. Do not use the speed change lever while the tool is
running. The tool may be damaged.
LIGHTING UP THE LAMP
CAUTION: Do not look in the light or see the source of light
directly.
Pull the variable speed trigger switch to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
OPERATING TIPS
You will extend the life of your bits and do neater work if you always put the bit in contact with the work
before pulling the trigger. During the operation, hold the tool firmly and exert light, steady pressure. Too
much pressure at low speed will stall the tool. Too little pressure will keep the bit from cutting and cause
excess friction by sliding over the surface. This can be damaging to both tool and bit.
Drilling with variable speed
The trigger controlled variable speed feature will eliminate the need for center punches in hard materials.
The variable speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are
able to keep the bit from “wandering”. You can increase the speed as the bit “bites” into the work by
squeezing the trigger.
Driving with variable speed
Variable speed drills will double as a power screwdriver by using a screwdriver bit in the drill mode. The
technique is to start slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing
to a stop. Prior to driving screws, pilot and clearance holes should be drilled.
