MODEL #71 SPRAY GUN
with #6 Air cap (Pressure)
CARE AND MAINTENANCE
It is not recommended that the entire spray gun be immersed in solvent for
any extended period. This precaution will prevent packings from becoming
dry and causing air leaks, as well as removing desirable lubrication.
It is not recommended that this spray gun be completely disassembled for
cleaning. Especially if the procedure outlined below is followed.
CLEANING SPRAY GUN & EQUIPMENT (Pressure Feed)
Step I - Release air pressure from pressure tank.
Step II - Back pressure as follows:
Loosen air nozzle and hold a cloth over same.
Using normal spraying air pressure, pull trigger and air pressure will force
material from gun passages and fluid line into pressure tank. Remove material
from pressure tank and replace with compatible solvent.
Step III - Tighten air nozzle and operate system as if painting
until clean solvent appears.
Step IV - Repeat back pressure procedure to clear solvent
from gun passages and fluid lines.
Step V - Wipe down the spray gun with compatible solvent.
This method obviously cleans not only the spray gun but the entire system.
