TOF-5B/-5RB & TOF-6B/-6RB AUTOMATIC SPRAY GUNS
BEFORE CARRYING OUT MAINTENANCE AND INSPECTION ALWAYS OBSERVE SAFETY WARNING
INDICATIONS.
ONLY AN EXPERIENCED PERSON WHO IS FULLY CONVERSANT WITH THE EQUIPMENT CAN DO MAINTE
NANCE AND INSPECTION.
FIRST RELEASE AIR AND PRESSURE FULLY ACCORDING TO ITEM NO. 3 OF “IMPROPER USE OF EQUIPMENT”
OF WARNING ON PAGE .
NEVER DAMAGE FLUID NOZZLE TIP, FLUID NEEDLE OR AIR CAP HOLES.
NEVER IMMERSE THE SPRAY GUN COMPLETELY IN LIQUIDS SUCH AS THINNER.
6. MAINTENANCE AND INSPECTION
THE FLUID PASSAGES OF THE GUN, MUST BE CLEANED THOROUGHLY AFTER EACH USE,
ESPECIALLY AFTER USE WITH BI-COMPONENT PAINTS. INCOMPLETE CLEANING CAN CAUSE
DEFECTIVE PATTERN SHAPE.
NEVER SOAK AIR CAP IN CLEANING LIQUID FOR EXTENDED PERIOD EVEN IF CLEANING.
NEVER USE METAL BRUSH TO CLEAN THE GUN.
1. Drain remaining paint from spray gun, into a suitable container. Spray a small amount of cleaning liquid to clean
uid passages and air cap set. Incomplete cleaning can cause failure of paern shape and uniform parcles.
2.
Clean each secon with brush soaked with cleaning liquid and wipe out with waste cloth. Do not immerse the
whole gun in cleaning liquid. Otherwise, it can damage the gun. When cleaning, never scratch any holes of air
cap set, uid nozzle or piston set.
3. Before disassembly, fully clean uid passages. During disassembly, do not scratch seat secon.
A_Disassemble piston set. First remove uid adjustment knob and pull it by holding end of piston. Ensure that
piston spring does not suddenly y out because uid adjustment knob is strongly pushed by piston spring.
(Use ring spanner and box wrench). Remove uid nozzle while piston set is kept
pulled backwards, in order to protect seated secon of uid nozzle and piston set.
6.1 CLEANING PROCEDURE
IMPORTANT
it can cause failure of piston operation.
Securely lock fluid adjustment knob with jam nut when fluid output has been decided, so that the fluid output is
not changed by vibrations caused by piston operation and the piston and the piston spring do not suddenly fly out
unexpectedly due to loosening of adjustment knob.
Be careful that the fluid adj. knob and pattern adj. knob could come off when they are completely opened.
Especially when air pressure is applied to them, they could fly out swiftly and could cause injury.
To adjust pattern adj. at the maximum, turn pattern adj. knob around 3 turns from fully closed position.
With TOF-5B/5RB it could be possible to have spits at start and stop, depending that is due to the type of paint
and painting conditions. To avoid failure, start to spray in advance and stop late.
5. HOW TO ADJUST
Adjust atomizing air pressure varies according to viscosity and paint property. Recommended air pressure is
between 2.5-4.0 bar. (Use higher air pressure to spray fine mist and lower air pressure to spray coarse mist).
For TOF-6B/6RB, set piston operating air pressure to 2.5 bar or more (CYL marked side).
When using the pressure feed tank, set its pressure to 2.0 bar or less.
There are two methods to adjust fluid output:
1. Adjust compressed air pressure to the pressure feed tank.
2. Open and close fluid adjustment knob of gun. Fluid output becomes zero when fluid adjustment knob of gun
is turned fully clockwise. Fluid output gradually starts increasing when fluid adjustment knob is turned 0.5 turn
counter-clockwise from zero point and fluid output stops increasing when fluid adjustment knob is 4 full turns
counter-clockwise.
The pattern becomes round, when the pattern adj. knob is completely closed. The pattern becomes oval, turning
the pattern adj. knob counter-clockwise. (TOF-5B/6B).
