WHEEL PITCH ADJUSTMENT
Loosen Blade Before Making These Adjustments!
In case the blade runs too low, or off the idler wheel,
adjust the wheel block to which the wheel is mounted.
To do this, loosen the two cap screws marked “1”
one-half turn and tighten two cap screws marked “2”
an equal amount.
To make similar adjustment on drive wheel at motor
end, it is necessary to loosen the two cap screws at
“3”, then make pitch adjustment by loosening two hol-
low head set screws at “4” and tighten two hollow
head set screws at “3”. The four cap screws should
then be tightened to hold motor plate in a rigid and
fast position.
If there is too much pitch on the wheel the blade will
run too high. This will cause the blade to become
distorted and the back of the blade will be rolled over,
also the wheel rim fl ange will show excessive wear.
To correct this condition, loosen two cap screws at
“2”, tighten two cap screws at “1”. Loosen two
cap screws at “4”, then make pitch adjustment by
loosening two hollow headset screws at “3” and
tightening two hollow head set screws at “4”. The
four cap screws should then be tightened to hold
motor plate in a rigid and fast position.
FRAME WEIGHT ADJUSTMENT
Place weight on slide bar at motor end of slide and
remove dash pot, before adjusting frame spring under
motor end, The frame spring should be adjusted
for approximately 10 Ibs. Use slide weight to make
fi nal feed adjustment. The cutting pressure,
which determines the feed, should not be increased
to a point where the blade starts to run sidewise while
cutting. Large stock will stand a heavier feed than
small stock.
BLADE BRUSHES
Brushes should be cleaned frequently in kerosene
and reversed to take advantage of both rows of bris-
tles.
For best results, replace worn, fi lled or sticky brushes
with new ones. In bolting brushes to angles, be sure
wire bristles are bent in same direction blade travels.
LUBRICATION
• The correct and adequate lubrication is a very
important factor in determining the life and serv-
ice to be obtained. It is imperative that all dust and
dirt should be removed before lubricating.
• Keep vise adjusting screw well lubricated with
a medium type of grease.
• The gears in the gear case are lubricated with
a metal penetrating type of grease that will not
channel. A small quantity of this lubricant can be
added through hole in side of gear case when
required.
• The electric motor has sealed-type ball bearings
and should be oiled at regular intervals accord-
ing to standard practices, when repacking, a high
grade medium type of grease should be used.
• Keep internal ring gear and pinion well greased
with a good quality fi ber type grease (medium
grade). For proper inspection and for greasing
these gears, it is necessary to remove the drive
wheel.
• Lubricate the motor pivot post with a few drops of
machine oil. If properly lubricated, the weight of
the motor will keep the belt tight, and allow easy
speed changes.
• Wheel ball bearings are lubricated by pressing
out the bearings and repacking them with a good
quality of ball bearing grease.
Keep machine clean and be sure no cuttings are
allowed to mix with lubricants, as this forms an
abrasive which is detrimental to the operation of
the machine.
Use only hydraulic oil for dash pot.
