Functional Description; Operation; Maintenance - Makita 6822 Instruction Manual

WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.

FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function on
the tool.
Depth adjustment
Fig.1
The depth can be adjusted by turning the locking sleeve.
Turn it in "A" direction for less depth and in "B" direction
for more depth. One full turn of the locking sleeve equals
1.5 mm change in depth.
Adjust the locking sleeve so that the distance between
the tip of the locator and the screw head is
approximately 1 mm as shown in the figures. Drive a trial
screw into your material or a piece of duplicate material.
If the depth is still not suitable for the screw, continue
adjusting until you obtain the proper depth setting.

Switch action
Fig.4
CAUTION:
Before plugging in the tool, always check to see
•
that the switch trigger actuates properly and
returns to the "OFF" position when released.
To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
For continuous operation, pull the switch trigger and
then push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
A speed control screw is provided so that maximum tool
speed can be limited (variable). Turn the speed control
screw clockwise for higher speed, and counterclockwise
for lower speed.
NOTE:
Even with the switch on and motor running, the bit
•
will not rotate until you fit the point of the bit in the
screw head and apply forward pressure to engage
the clutch.
Reversing switch action
Fig.5
CAUTION:
Always check the direction of rotation before
•

operation.

Use the reversing switch only after the tool comes
•
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
This tool has a reversing switch to change the direction
of rotation. Move the reversing switch lever to the "FWD"
position for clockwise rotation or the "REV" position for
counterclockwise rotation.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
Installing or removing the bit
Pull the locator out of the locking sleeve while turning the
locator slightly. Then grasp the bit with a pair of pliers
and pull the bit out of the magnetic bit holder. Sometimes,
it helps to wiggle the bit with the pliers as you pull.
Fig.6
To install the bit, push the bit firmly into the magnetic bit
holder. Then install the locator by pushing it firmly onto
the locking sleeve while turning the locator slightly.
Fig.7
OPERATION
Fit the screw on the point of the bit and place the point of
the screw on the surface of the workpiece to be fastened.
Apply pressure to the tool and start it. Withdraw the tool
as soon as the clutch cuts in. Then release the switch
trigger.
CAUTION:
When fitting the screw onto the point of the bit, be
•
careful not to push in on the screw. If the screw is
pushed in, the clutch will engage and the screw will
rotate suddenly. This could damage a workpiece or
cause an injury.
Make sure that the bit is inserted straight in the
•
screw head, or the screw and/or bit may be
damaged.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
