The Clamp Pressure should be approx 600
psi. This can be read by completely lower-
ing the clamp. If the pressure is too low, the
saw motor will start softly or hesitate. The
relief valve for this is located at the top of the
control block. See Fig 13.
The Saw Feed Pressure should be set at
approximately 95-110 psi. If it is adjusted too
high, the saw motor will stick and stall. If it is
too low it may feed slowly or it may pulse. Try
to adjust it as high as possible without stalling
the saw. The relief valve is located on the
side of the control block, the hand knob. See
Fig 14.
MAINTENANCE
The bearings should be greased with one
shot of grease every 200 hours of use.
The engine must be maintained according
to the instructions of the engine manual.
The saw chain (.404) must be sharpened or
replaced whenever it is dull. If it dulls on one
side it may pull the bar to the side and cause
binding. This machine’s 20” bar requires
and 78 tooth drive link for its chain. The
hydraulic uid is standard 46 weight hydraulic uid and should
be added daily to compensate for the oiler usage. Keep the soft
start pivot greased daily, see Fig 15. Change
the hydraulic lter every 250 hours of use.
Use Zinga lter # HE-10L. See Fig 16. Check
the air lter every 20 hours. Clean them if
dirty. Change the engine oil every 50 running
hours.

Your machine has 2 dierent ways it could be set up for the bar
oiling, depending on how the machine was ordered from the
factory.
If your machine is equipped with a standard
oiler from the machine hydraulics, your
adjustments knob is on top of the control
block, see Fig. 17. Adjust clockwise to
decrease oil ow and counterclockwise to
increase oil ow. Your chain should be moist
with oil. If oil is misting away from chain while
it is engaged, your ow should be slightly
decreased. If your chain is not freely moving on the bar and
seems restricted or hot, slightly increase your oil ow.
If your machine is equipped with a dedicated system, the ow
control for the dedicated oiler is located on the oiler pump. See
Fig. 18 adjust this knob counterclockwise this will increase ow
and clockwise will decrease ow.
