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.

like. Discoloration, deformation or cracks may result.
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.

NOTE:
• Some items in the list may be included in the tool
package as standard accessories. They may differ
from country to country.
Noise
The typical A-weighted noise level determined according
to EN62841:
Model DFS441
Sound pressure level (L
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
Model DFS451
Sound pressure level (L
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
• The declared noise emission value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
• The declared noise emission value(s) may also be
used in a preliminary assessment of exposure.
WARNING:
• Wear ear protection.
• The noise emission during actual use of the power
tool can differ from the declared value(s)
depending on the ways in which the tool is used
especially what kind of workpiece is processed.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of
ENG905-1
): 70 dB (A) or less
pA
): 71 dB (A)
pA
ENG907-1
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).
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN62841:
Work mode: screwdriving without impact
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
• The declared vibration total value(s) 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 value(s)
depending on the ways in which the tool is used
especially what kind of workpiece is processed.
• 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).
