Making Timed Deposits of Medium to Thick Fluids

(Model 900)
You are now ready to test the pre-filled, nontoxic, blue test fluid. This
material is representative of thick, non-leveling fluids like sealants,
pastes or greases.
Check your initial settings:
A) Air gauge reads 30 psi.
B) Timer is set at #7.
C) Green tapered tip is on the test barrel.
D) Power and timer bypass switches are on.
Holding the barrel as shown, rest the tip on a piece of paper. Press
the foot pedal until the tip fills and some fluid is pushed out onto the
paper. Repeat this whenever you change to a new tip.
With the tip filled, turn off the timer bypass switch (yellow light out).
Take the Dot Test sheet and put the tip on a 1/4" circle, holding the
barrel as shown. Press the foot pedal. Check the dot size. Make
several more similar dots and note the size consistency.
Remember – When the yellow timer bypass switch is on, a continuous
flow of material will occur as long as the foot pedal is pressed. The
yellow light must be off to make timed deposits.
