TROUBLE CHARTS - Continued
1. 200283 feed
A. Feed control timing ring 200285 should be at bottom, that is, neutral
position, when feed knob 200286 is turned to the left against stop pin,
which is zero position. Fig. 3 shows feed control timing ring on center or
positioned end feed
in zero position. If 200285 ring is in uppermost position, when 200286
cannot be controlled
knob is in zero position, the feed is fully open and is uncontrollable. See
B. To set 200286 knob to correct position raise knob over stop pins and turn
to the left as far as it will go. Then lower knob into place. Make sure
knob remains in correct position when replacing 275026 guard. See
2. WORN 200283
A. To check for oil leaks at this point, remove 275026 guard (Fig. 3) and
303019 tubing coil (Fig. 7). Remove a 1/8" fitting on 700057 lift cylinder

B. If no more than normal feed down is evident (See Page 10 Item 3B for
frame cannot be
normal feed down), then leak must be in 200283 feed timing case cover,
and this part must be replaced. See Fig. 7.
C. 200283 feed timing case cover is always fitted with 200277 feed cylinder
(Figs. 7 and 3) and shipped
as complete assembly No. 700036.
3. Worn 4 piston IN
A. First check for abnormal feed down of saw frame due to leak in 200283
200261 control valve
feed timing case cover (See Item 2A, Page 11).
B. If abnormal feed down is still evident, the control valve piston 300354 is
probably worn and the valve must be replaced.
C. As the control valve piston 300354 is fitted to the Control valve 200261,
these parts must be purchased as complete assembly No. 700015.

A. Remove 300403 cap on top of 200261 control valve and clean ball and
valve ball beneath
30043 cop on control
B. Reseat by topping ball in place in seat with soft Steel rod before
causing oil leak,
replacing 300403 cap. See Fig. 4
through ball check.
2. Dirt in 300411
A. Remove 300414 cap. Then measure adjusting screw projection (usually
flexible feed valve
about /4") so that it can-be replaced in former position. Remove 300419
