Operation; Maintenance - Makita 4191D Betriebsanleitung

OPERATION

Hold the tool firmly. Set the base plate on the workpiece
to be cut without the wheel making any contact. Then
turn the tool on and wait until the wheel attains full speed.
Feed water to the wheel by adjusting the water cock to
obtain a gentle flow of water. Move the tool forward over
the workpiece surface, keeping it flat and advancing
smoothly until the cutting is completed. Keep your cutting
line straight and your speed of advance uniform.
For fine, clean cuts, cut slowly. (When cutting glass plate
5 mm thick, cut at about 250 mm/min. When cutting tile
10 mm thick, cut at about 300 mm/min.) Also slow down
as you complete a cut to avoid breaking or cracking the
workpiece being cut. (Fig. 14)
CAUTION:
• Be sure to hold the workpiece firmly down on a stable
bench or table during operation.
• Do not twist or force the tool in the cut, or the motor
may be overloaded or the workpiece may break.
• Do not use the tool with the wheel in an upward or side-
ways position.
• When cutting glass plate, it is recommended to attach a
rubber plate (optional accessory) on the base of the
tool to prevent the workpiece surface from being
scratched.
• The wheel for this tool is a wet-type wheel for glass and
tile applications. Be sure to feed water to the wheel dur-
ing operation.
• If the cutting action of the wheel begins to diminish,
dress the cutting edge of the wheel using an old dis-
carded coarse grit bench grinder wheel or concrete
block. Dress by pressing lightly on the outer edge of the
wheel.
NOTE:
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.

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.
After use
Brush off accumulation of dust on the base.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always

Noise
The typical A-weighted noise level determined according
to EN60745:
Sound pressure level (
Sound power level (
Uncertainty (K): 3 dB (A)
Wear ear protection
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN60745:
Work mode: Concrete cutting
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration emission value has been mea-
sured 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 oper-
ator 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).
