There are no components of your blender that require periodic maintenance. However, over the
years, blenders may be subjected to abuse or difficult conditions, and accuracy can suffer. To
maintain control over the cost of expensive color and additives, you must maintain accuracy. We
recommend that blenders be examined once a year, and all necessary repairs be made to insure
continued accuracy.
To be accurate, gates must open and close freely, quickly, and completely. Check
for wear on the slide gate guide rods. Check cylinder clevis adjustment for correct
closing of the gate. A gate should close just enough to block the hole, but no further.
It is best if they do not pass over the far edge of the opening as this might catch and
jam on a pellet. Check that the clevis pin connecting the air cylinder is intact, not
broken or worn through. Check for correct air pressure, tight fittings, and no
damaged or crimped air lines.
Check for smooth correct operation of the dump flap. Hinge points should not be
worn. Gate should overlap the forward edge enough to prevent dribble when closed,
even when closed against pellets. Space at the rear of the flap should allow for static
build up of pellets on the rear edge of the dump flap without interfering with the
closing of the flap. Again, if you see evidence of these problems, newer design parts
are available to solve these problems. Check that the flap closes fully, and closes
softly. The soft close is adjustable.
FREE MOVEMENT OF WEIGH BIN
Carefully examine all the parts of the weigh bin and the bin hanging bracket to be
sure that nothing touches any fixed parts. A quarter (1/4) inch of space should exist
on all sides of the weigh bin. Over the years, windows and guards have been added,
and this has required that the weigh bin size be reduced to maintain 1/4 inch
clearance per side. Be sure you do not have an older larger bin installed where
windows have been added. A light touch of the bin should show a change in the
weight readout. Remove the touch and the display should return to exactly the same
number, plus or minus 1 or 1/10 gram depending on model. Only the last digit should
drift, or vary, and by no more than one count. If ANY interference is detected, it
MUST be fixed.
No bent blades. No SHARP blades. Bent blades might break off and severally
damage your process screw. Sharp blades are a safety hazard. Replace if mix
blades are not perfect.
The blade assembly should slip on and off the motor shaft easily. The need to use
excessive force to remove the mixer assembly may bend the blades and they may
eventually break off. Correct this if it is a problem.
