Operation; Maintenance - Makita DJR189 Instruction Manual

To install the recipro saw blade, always make sure that
the blade clamp lever (part of the blade clamp sleeve)
is in released position before inserting the recipro saw
blade. If the blade clamp lever is in fixed position, rotate
the blade clamp lever in the direction of the arrow so
that it can be locked at the released positon.
► Fig.5: 1. Blade clamp lever 2. Fixed position
3. Released position
Insert the recipro saw blade into the blade clamp as far
as it will go. The blade clamp sleeve rotates and fixes
the recipro saw blade. Make sure that the recipro saw
blade cannot be extracted even though you try to pull
it out.

CAUTION:
If you do not insert the recipro saw
blade deep enough, the recipro saw blade may be
ejected unexpectedly during operation. This can
be extremely dangerous.
To remove the recipro saw blade, rotate the blade
clamp lever in the direction of the arrow fully. The reci-
pro saw blade is removed and the blade clamp lever is
fixed at the released position.

CAUTION:
Keep hands and fingers away from
the lever during the switching operation. Failure
to do so may cause personal injuries.
NOTE: If you remove the recipro saw blade without
rotating the blade clamp lever fully, the lever may not
be locked in the released position. In this case, rotate
the blade clamp lever fully again, then make sure that
the blade clamp lever locked at the released position.
NOTE: If the blade clamp lever is positioned inside
the tool, switch on the tool just a second to let the
blade out. Remove the battery cartridge from the tool
before installing or removing the recipro saw blade.
Hook
Optional accessory
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
CAUTION:
When hanging the tool, set the
lock-off button in position to lock the switch
trigger. (See the section for switch action.)
CAUTION:
Never hang the tool at high or
potentially unstable location.
CAUTION:
Do not hook the tool on your belt
or other accessories. The recipro saw blade may
contact your body and cause personal injury.
CAUTION:
Use the hanging/mounting parts
for their intended purposes only. Using for unin-
tended purpose may cause accident or personal
injury.
► Fig.8: 1. Groove 2. Screw 3. Hook
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.

OPERATION

CAUTION:
Always press the shoe firmly
against the workpiece during operation. If the
shoe is removed or held away from the workpiece
during operation, strong vibration and/or twisting will
be produced, causing the blade to snap dangerously.
CAUTION:
Always wear gloves to protect
your hands from hot flying chips when cutting
metal.
CAUTION:
Be sure to always wear suitable
eye protection which complies with current
national standards.
CAUTION:
Always use a suitable coolant
(cutting oil) when cutting metal. Failure to do so will
cause premature blade wear.
CAUTION:
Do not quirk the blade during
cutting.
Press the shoe firmly against the workpiece. Do not
allow the tool to bounce. Bring the recipro saw blade
into light contact with the workpiece. First, make a pilot
groove using a slower speed. Then use a faster speed
to continue cutting.
► Fig.9
NOTICE:
Do not cut the workpiece with the shoe
away from the workpiece. Doing so increases the
reaction force which may break the recipro saw blade.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE:
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 or Factory Service
Centers, always using Makita replacement parts.
