Maintenance - Makita AN250HC Instruction Manual

Pin-driving of concrete
WARNING:
Use hardened pins only for concrete.
•
Using other purposed pins may cause serious
injuries. Do not pin directly on the concrete.
Failure to do so may cause concrete fragments to
fly off or pins to strike back, causing serious
injuries.
When driving pins, hold the tool so that it stands
•
upright to the driving surface.
Slanted pin-driving may cause concrete fragments
to fly off or pins 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 pins so that the penetration amount
into concrete ranges 15 mm (9/16") - 20 mm (13/16").

CAUTION:
Use this tool only for soft concrete built up not so
•
long before. Using on the hard concrete may cause
pin bending or pin-driving to insufficient depth.
When the penetration amount into concrete is
•
required more than 20 mm (13/16"), driving pins to
the sufficient length may not be obtained. Pins may
be driven too shallow causing unstable workpiece,
resulting in personal injury and damage to property.
