Maintenance - Makita BTP130 Bedienungsanleitung

Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
CAUTION:
Make sure that the driver bit is inserted straight in
•
the screw head, or the screw and/or bit may be
damaged.
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
NOTE:
When driving wood screws, predrill pilot holes to
•
make driving easier and to prevent splitting of the
workpiece. See the chart.

Drilling operation
First, set the action mode changing lever so that the
pointer points to to the
mark is for low speed rotation and the
high. The adjusting ring can be aligned in any torque
levels for this operation. Then proceed as follows.
Before operation, always make sure that the lever is
correctly set to your desired mode mark and use the tool
at an appropriate speed for your work.
Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and hammer at
the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be drilled
dry.
CAUTION:
Pressing excessively on the tool will not speed up
•
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.

at the time of hole break through. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.
A stuck bit can be removed simply by setting the

reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you
do not hold it firmly.
Always secure small workpieces in a vise or similar

battery cartridge is removed before attempting to
perform inspection or maintenance.
Replacing carbon brushes
Fig.16
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.
Use a screwdriver to remove two screws then remove
the rear 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 cap of the carbon
brushes. Take out the worn carbon brushes, insert the
new ones and replace the carbon brush cap in reverse.
Fig.19
Make sure that the carbon brush cap have fit into the
holes in brush holders securely.
Fig.20
Reinstall the rear cover and tighten two screws securely.
After replacing brushes, insert the battery cartridge into
the tool and break in brushes by running tool with no
load for about 1 minute. Then check the tool while
running and electric brake operation when releasing the
switch trigger. If electric brake is not working well, ask
your local Makita service center for repair.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
