Maintenance - Makita AN930H Betriebsanleitung

• When nailing, hold the tool so that it stands upright to
the driving surface.
Slanted nailing may cause nails to strike back, causing
serious injuries.
• Do not use for fastening a corrugated plate or the C-
shaped steel directly. It may cause nails to strike back,
causing serious injuries.
• Do not use the tool for nailing on ceiling or roof.
Choose and use nails more than 10 mm longer than total
thickness of all workpiece to be fastened by referring to
the table below.

(Fig. 24)
CAUTION:
• Depending on the hardness and total thickness of all
workpiece in combination to be fastened, enough
fastening may not be obtained. Nailing on steel plate to
excessive depth may extremely reduce the fastening
force. Before nailing, adjust the nailing depth properly.
• In the nailing on the steel plate, the driver may be
clogged due to susceptibility to wear. When it is worn,
sharpen it or replace it with a new one.
Nailing of concrete
WARNING:
• Use hardened nails only for concrete.
Using other purposed nails may cause serious injuries.
Do not nail directly on the concrete or do not use to
fasten directly the steel plate to the concrete. Failure to
do so may cause concrete fragments to fly off or nails
to strike back, causing serious injuries.
• When nailing, hold the tool so that it stands upright to
the driving surface.
Slanted nailing may cause concrete fragments to fly off
or nails to strike back, causing serious injuries.
• Do not use on the surface that objects hang from, such
as area where hangers for sewer pipe, dust pipe etc.
are set up.
Choose and use nails so that the penetration amount into
concrete ranges 10 mm - 15 mm by referring to the table
below.

CAUTION:
• Use this tool only for soft concrete built up not so long
before. Using on the hard concrete may cause nail
bending or nailing to insufficient depth.
• When the penetration amount into concrete comes to
more than 15 mm, nailing to the sufficient length may
not be obtained.

Cutting off the sheet (Fig. 26)
CAUTION:
• Always disconnect the hose before cutting off the
sheet.
Tear off the output sheet in the direction of the arrow
when using the sheet collated nails.
Jammed nailer (Fig. 27 & 28)
CAUTION:
• Always disconnect the air hose and remove the nails
from the magazine before cleaning a jam.
When the nailer becomes jammed, do as follows:
After depressing the latch lever and open the door, open
the magazine cap and remove the nail coil. Insert a small
rod or the like into the ejection port and tap it with a
hammer to drive out the nail jamming from the ejection
port. Reset the nail coil and close the magazine cap.

MAINTENANCE

CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
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 (Fig. 29)
When not in use, disconnect the hose. Then cap the air
fitting with the cap.
Storage (Fig. 30)
When not in use, the nailer should be stored in a warm
and dry place.
Maintenance of compressor, air set and
air hose
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.
(Fig. 31)
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.
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.
