Speed Change; Adjusting The Fastening Torque - Makita DHP483 Instruction Manual

CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.

Adjusting the fastening torque

► Fig.9: 1. Action mode changing ring 2. Adjusting
ring 3. Graduation 4. Arrow
The fastening torque can be adjusted in 20 levels by turning the adjusting ring. Align the graduations with the arrow
on the tool body. You can get the minimum fastening torque at 1 and maximum torque at 20.
Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which
torque level is required for a particular application. The following shows the rough guide of the relationship between
the screw size and graduation.

To change the speed, switch off the tool first. Push
the speed change lever to display "2" for high speed
or "1" for low speed but high torque. Be sure that the
speed change lever is set to the correct position before
operation.
If the tool speed is coming down extremely during the
operation with display "2", push the lever to display "1"
and restart the operation.
Selecting the action mode
CAUTION:
your desired mode mark. If you operate the tool
with the ring positioned halfway between the
mode marks, the tool may be damaged.
CAUTION:

ficulty to slide the action mode changing ring. In
this case, switch on and run the tool for a second
at the " " position, then stop the tool and slide
the ring to your desired position.
