SAFETY
This applicator is a quality product for the professional user; it is designed for
high duty cycles over long operating periods. As compressed air is used as the
power source, operator fatigue is minimal, but it must be remembered that
compressed air can be dangerous when used incorrectly. The user should take
time to read and understand these operating instructions fully. Failure to do so,
could lead to serious bodily injury.
ALWAYS
• USE PROTECTIVE EYE EQUIPMENT WHEN OPERATING.
• DISCONNECT THE AIR SUPPLY BEFORE STARTING ANY MAINTENANCE/CLEANING TASKS.
NEVER
• CONNECT THE APPLICATOR TO AN AIR SUPPLY WHICH CAN EXCEED 145 psi (10 BAR)
• IMMERSE THE GUN IN SOLVENT.
• OPERATE THE GUN WITH LOOSE, BROKEN OR MISSING PARTS.
• CARRY THE GUN BY THE AIR PIPE.
• USE DAMAGED CARTRIDGES OR THE WRONG TYPE OF CARTRIDGE IN THE APPLICATOR.
• FIT A REGULATOR WITH A HIGHER PRESSURE VALUE.
It is recommended that ear protection is used for Mk5b type guns.
CONNECTION
Check the supply pressure. For optimum performance the supply pressure must
be greater than 100 psi (6.8 bar) and less than 145 psi (10 bar).
The applicator will work at lower supply pressures, but flow rates could be
reduced and may vary.
Connect the applicator to a suitable compressed air source using the nut and tail
supplied, or with a suitable fitting. All applicators are fitted with a male ¼” BSP
thread.
OPERATION/CONTROLS
A -
Internal Pressure Regulator
The internal pressure regulator controls the material flow rate and ensures a
stable flow of sealant is maintained. To increase the flow of sealant, turn the
knob in a clockwise (+) direction. To decrease the flow, turn the knob in an
anticlockwise (-) direction.
The regulator is colour coded to designate the maximum pressure that will be
allowed in to the applicator barrel, regardless of the line in pressure.
Blue = 50 psi (3.4 bar) Yellow = 75 psi (5.1 bar) Orange = 100 psi (6.8 bar)
B -
Trigger
By pulling the trigger, a cushion of compressed air is built up inside the
applicator, which initiates the flow of material. On releasing the trigger, the
sealant flow ceases as the compressed air escapes rapidly by a quick exhaust
valve at the rear of the gun.
C -
Plunger Return Button (Where fitted)
Press and hold the plunger return button (C), then pull the trigger (B).
This will pull back the plunger rods automatically ready for the next cartridge.
If the applicator is not fitted with the air return button, manually pull back the
plungers using the indicator knob (D).
D - Indicator/Return Knob
This gives a visual indication of how much material is remaining in the cartridge
during use. For guns not fitted with air return, the return knob is used to
manually pull the plungers back.
MAINTENANCE
DAILY: Wipe the applicator using the adhesive manufactures recommended
solvent before it has time to set. Special care should be taken to make sure no
residue is left on the rods.
WEEKLY: Check the plungers and all external bolts/screws are tight. Tighten if
found to be loose.
MONTHLY: Place a small amount of oil in the air pipe to keep the internal seals
and pistons lubricated.
NOTE
Tested in accordance with European Machinery Regulations (1.1.95)
Mk5b pneumatic applicator has A-weighted sound pressure levels in
excess of 70dB (A).
Series 2 pneumatic applicator has A-weighted sound pressure levels
less than 70dB (A).
