Replace bit in clean surroundings to prevent dust and dirt
from getting onto internal components.
Removing Bit (Fig. 21)
1. Disconnect hose and remove all loaded screws.
2. Use hex wrench to loosen the four hex bolts, and then
remove top cap.
- The top cap spacer is removable, but please leave it
on the driver.
- If top cap gasket is removed with top cap, be careful
not to misshapen it, and be sure to put it back when
reassembling.
3. Insert the hex wrench into the bit channel of the driver
guide, and push out the piston assembly. (Fig. 22)
4. Use an eyeleteer, etc., to remove rubber ring (white)
from unloaded piston assembly.
- As the new bit comes with a white rubber ring, the
old one can be cut out with a cutter knife, etc. if it is
difficult to remove. (Fig. 23 & 24)
5. Next, extract pin from piston assembly. (Fig. 25)
6. Lower the piston, and then remove the piston cap and
driver bit. (Fig. 26)
Mounting Bit
1. Mount new driver bit onto piston. (Fig. 27)
2. Next, mount piston cap onto piston assembly.At this
point, make sure that piston assembly and piston cap
holes are aligned. (Fig. 28)
- Mount piston cap with hollowed side up as per
diagram.
3. Pass pin through piston assembly. (Fig. 29)
4. Mount rubber ring onto piston assembly. (Fig. 30)
5. Align the bit shape with the shape of driver's bit
channel and then insert bit. (Fig. 31)
6. Mount top cap onto driver and insert four hex bolts into
holes. (Fig. 32)
7. Firmly tighten hex bolts using hex wrench. At this
point, tighten in order [(1) to (4)] shown by arrows.
(Fig. 33)
- Prescribed tightening torque is between 7.5 and
8.5 N·m
After completing bit replacement, fully check to see that
there are no abnormalities, and then commence driving
screws.
Drain tool
Remove the hose from the tool. Place the tool so that the
air fitting faces down to the floor. Drain as much as
possible.
Cleaning of tool
Iron dust that adhere to the magnet can be blown off by
using an air duster.
Cap
When not in use, disconnect the hose. Then cap the air
fitting with the cap. (Fig. 34)
Storage
When not in use, the tool should be stored in a warm and
dry place.
Maintenance of compressor, air set and air hose. (Fig. 35
& 36)
After operation, always drain the compressor tank and the
air filter. If moisture is allowed to enter the tool, It may
result in poor performance and possible tool failure.
Check regularly to see if there is sufficient pneumatic oil in
the oiler of the air set. Failure to maintain sufficient
lubrication will cause O-rings to wear quickly. (Fig. 37)
Keep the air hose away from heat (over 60°C, over
140°F), away from chemicals (thinner, strong acids or
alkalis). Also, route the hose away from obstacles which it
may become dangerously caught on during operation.
Hoses must also be directed away from sharp edges and
areas which may lead to damage or abrasion to the hose.
(Fig. 38)
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.
ACCESSORIES
CAUTION:
• These accessories or attachments are recommended
for use with your Makita tool specified in this manual.
The use of any other accessories or attachments might
present a risk of injury to persons. Only use accessory
or attachment for its stated purpose.
If you need any assistance for more details regarding
these accessories, ask your local Makita Service Center.
• Air hoses
• Safety goggles
Noise
The typical A-weighted noise level determined according
to EN792:
Sound pressure level (L
Sound power level (L
Uncertainty (K): 3 dB (A)
Wear ear protection.
Vibration
The vibration emission value determined according to
EN792:
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).
