Operation; Maintenance - Makita BFR440 Betriebsanleitung

Removing screw strip
To remove the screw strip, just pull it out in the direction of
the arrow. (Fig. 10)
If you depress the reverse button, you can pull out the
screw strip in the reverse direction of the arrow. (Fig. 11)
Carry hook (Fig. 12)
The carry hook is convenient for temporarily hooking the
tool. It can be installed on either side of the tool.
When removing the carry hook, widen it by pressing its
right ends ON BOTH SIDES in the directions of arrow (1)
and raise it in the direction of the arrow (2).

OPERATION

Driving operation (Fig. 13)
Switch on the tool by pulling the switch trigger. Hold the
tool squarely and firmly up against the driving surface. A
screw will be automatically carried to the driving position
and fastened.
CAUTION:
• Always check the bit carefully for wear before driving
operations. Replace a worn bit or poor fastening may
result.
• Always hold the tool squarely against the driving sur-
face. Holding it at an angle may damage the screw
heads and cause wear on the bit. This may also lead to
poor fastening.
• Always keep the tool firmly against the driving surface
until the driving is over. Failure to do so may cause
insufficient fastening of screws.
• Be careful not to drive a screw onto another screw
already fastened.
• Do not operate the tool without screws. It will damage
the driving surface.
• If the feeder box does not work smoothly when driving
screws, spray car wax (spray type) on the sliding sur-
faces. Never lubricate it.
Driving in corner (Fig. 14)
This tool can be used to drive at a position 15 mm away
from the wall as shown in the figure.
CAUTION:
• Driving at a position closer than 15 mm to the wall or
driving with the stopper base in contact with the wall
may damage the screw heads and cause wear on the
bit. This may also lead to poor fastening of screws and
malfunction of the tool.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and the bat-
tery 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.
Replacing carbon brushes
Replace when they wear down to the limit mark. Keep the
carbon brushes clean and free to slip in the holders. Both
carbon brushes should be replaced at the same time. Use
only identical carbon brushes. (Fig. 15)
Loosen the thumb screws which secure the casing. Pull
out the casing in the direction of the arrow. (Fig. 16)
Use a screwdriver to remove two screws then remove the
front cover. (Fig. 17)
Raise the arm part of the spring and then place it in the
recessed part of the housing with a slotted bit screwdriver
of slender shaft or the like. (Fig. 18)
Use pliers to remove the carbon brush caps of the carbon
brushes. Take out the worn carbon brushes, insert the
new ones and replace the carbon brush caps in reverse.
(Fig. 19)
Make sure that the carbon brush caps have fit into the
holes in brush holders securely. (Fig. 20)
Reinstall the front cover and tighten two screws securely.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.

Noise
The typical A-weighted noise level determined according
to EN60745:
Sound pressure level (L
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
Wear ear protection.
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN60745:
Work mode: screwdriving without impact
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration emission value has been
measured in accordance with the standard test method
and may be used for comparing one tool with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the power
tool can differ from the declared emission value
depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of exposure in
the actual conditions of use (taking account of all parts
of the operating cycle such as the times when the tool
is switched off and when it is running idle in addition to
the trigger time).
