OPERATING INSTRUCTIONS - Continued
The single lever control makes this machine very simple to operate with a few minutes of practice. Put stock to be cut in
machine and tighten securely in vise with saw frame in Up position. Vise tightening wrench furnished is of sufficient
length to exert adequate pressure without undue strain. Then open the feed dial, which is on the right hand side of the
machine, to normal feed. See suggested feeds on chart located on machine beneath Feed Control Dial (200286). Now
push the control lever down to the lowest position. This will give a rapid traverse of the saw frame downward. Raising or
lowering slightly will control the rate of down travel. When the saw blade has approached to within 1/4" above the stock,
bring the lever up to Clutch position.
NEVER PLACE LEVER IN CLUTCH POSITION TO START THE RECIPROCATION WHEN THE
BLADE IS RESTING ON THE WORK. Always allow 1/4 for the blade to feed down to the work
otherwise you are likely to break blades.
Each range covers three speed: High 85, 110, 150; low 45, 60, 80. To go from high to low range, remove belt guard and
shift Poly Vee belt on step pulleys.
Gear shift lever is located on top of gear case cover. HIGH SPEED should be used for cold rolled steel, pipe, structural
shapes and easily machineable stock. The medium and low speeds are for harder stock. Shifting from one speed to
another should be done with the clutch engaged: that is, with the saw frame reciprocating.
When machine is new, gear teeth may be a little hard to mesh. Shifting should be done quickly, especially when shifting
from low to high gear. If shift lever stops in a neutral position, it is best to return to lower gear and then shift rapidly
across to high gear. Shift lever should not be forced. It may be necessary, at first, to throw clutch out of engagement
momentarily and shift the lever before gears have entirely stopped running.
FLEXIBLE AND POSITIVE FEED:
Two feeds are available -- positive and flexible. To put machine in flexible feed, turn petcock (400163) all the way out
(counterclockwise). To put machine in positive feed, turn petcock all the way in (clockwise). (See cross section drawing
No. 4.) With machine set on flexible feed the pressure is automatically regulated and feed is increased or decreased in
accordance with resistance against the blade. This allows blade to advance more rapidly through a light section of metal
and reduces feed during the cutting of a heavy section. Thus, in cutting round bar stock, feed will be greater at the
beginning and end of cut than in the center. Conversely, in cutting tubing the feed will be less at the beginning and end
of cut and will automatically increase through the center of the cut where the area of solid metal presented to the blade is
This flexible control should be used in conjunction with the graduated feed dial, and it will be found that feed setting can
be increased over feed numbers used with the positive feed as suggested below. The closing of the pet cock as
mentioned above immediately changes the feed to a positive feed, metering out on exact quantity of oil on each cutting
stroke as determined by the setting of the feed dial.
See feed chart located on machine beneath Feed Control Dial (200286) for recommended feeds on various sizes and
kinds of material.
Operator will quickly become familiar with rates of feeds for fastest production consistent with accuracy and reasonable
