metal portion of the mallet. Use the rubber capped end only to
prevent possible injury and/or damage to the Tool.

Do not drive fasteners into thin boards or near corners and
edges of work piece. Fasteners can be driven through or away
from work piece and hit someone.

Do not use Tool as a hammer.

Air supply hoses should have a minimum working pressure
rating of 150 psi or 150 percent of the maximum pressure pro-
duced in the power source, whichever is higher.
•
Check all hoses before connecting to ensure that they are free
from dirt, grit, or particles that could alter the performance of
the tool.

An airline Filter and In-Line Air Regulator adjustable to 125 psi
max are required.

NEVER use a defective tool. Replace worn or damaged parts
immediately. Be sure that the Safety Trigger and operating
mechanisms operate correctly and that all screws and seals are
securely tightened at all times.
METHODS OF OPERATION
After connection with power source is made, check to be sure that
the airline Regulator pressure is 70‑90 psi. Note: Some materials
may require a higher pressure in order to countersink the fastener.
Harder Material Flooring requires more pressure than typical Oak
or Maple. Face Nailing requires approximately 5 psi or more than
Angle Nailing.
Ensure that Tool is in proper working order and that there is no
leaking of air. If there is an air leak, Disconnect Immediately! Ar‑
range for repairs by a Hitachi authorized service center.
After being sure Tool is operable, place Tool in position to be used.
Always place the Tool in proper position against the flooring to be
fastened before depressing the trigger and striking the ram.
