WARNING
During materialing, be sure to wear protective cover such as glasses, mask or gloves to avoid serious
injury caused by material or solvent which might enter your eyes or you might inhale.
CAUTION
Before you use new flow gun for the first time, clean its inside. If not done, rust preventive inside gun can
cause sealing failure.
ATTENTION
As fluid pressure increases, fluid output increases with increasing wear on parts. For longer life span of
flow gun, adjust fluid pressure as low as you can, maintaining satisfactory fluid output.
CLEANING AND MAINTENANCE
In order to get longer lifetime of flow gun and good performance at the next job, fully clean its inside with
cleaning liquid which is compatible with material used, after you finish the job.
WARNING
During materialing, be sure to wear protective cover such as glasses, mask or gloves to avoid serious
injury caused by paint or solvent which might enter your eyes or you might inhale.
Be sure to stop pump and reduce fluid pressure down to 0 pressure before disassembling flow gun.
Only an experienced person who is fully conversant with the equipment can do maintenance and inspec-
tion.
CAUTION
Never use commercial or other parts instead of ANEST IWATA original spare parts.
No damage should be made on
