Maintenance; Service Information - DeWalt DWMT70779 Instruction Manual

MAINTENANCE

WARNING: Shut off air compressor, release all pressure
by depressing trigger, and disconnect power source before
disassembly or removal of any part of the gun or attached
components.
CAUTION: Always exercise extreme care when using any solvent
or thinner. Never clean the gun near fire, flame, or any source of heat
or sparks. Properly dispose of used cleaning materials.
CAUTION: DO NOT soak the entire spray gun in solvent or
thinner for a long period of time as this will destroy lubricants
and possibly impair operation. NEVER use lye or caustic alkaline
solution for cleaning. Such solutions will attack aluminum alloy
parts of the gun.
It is important that the spray gun be cleaned after each use.
Cleaning
1. Empty material from gravity feed cup and replace with a
suitable solvent or thinner.
2. Operate trigger until all material traces have disappeared
and gun is thoroughly clean.
3. Clean air cap with a brush.
4. Wipe the exterior of the spray gun with a solvent soaked
cloth or use cleaning brush(es) provided to remove any
accumulated material.
IMPorTanT: Make certain that the air cap and fluid nozzle are
kept clean at all times. If necessary, remove these two components
and soak them in solvent. DO NOT use hard objects to clean
clogged holes. The smallest amount of damage may cause
irregular spray pattern.
noTe: If the fluid nozzle is to be removed for thorough cleaning,
squeeze the trigger to prevent damage of the fluid needle tip when
unscrewing the nozzle.
Lubrication
Lubrication procedures must be observed after thoroughly cleaning the
gun to ensure effective, high quality performance of spray gun.
1. Lubricate working points with straight mineral oil, or castor oil.
2. Periodically, place a few drops of oil on tapered sections
of the fluid nozzle to ensure easy operation of the air cap.
When spraying water base materials, coat the fluid nozzle
inside and outside with straight mineral oil after each use.
3. Outer diameter of the needle sleeve in the fluid needle
assembly must be lubricated occasionally with straight mineral oil.
