2. Drain, clean, rell the reservoir and change the oil
lter after the rst month of operation; every six (6)
months thereafter. Clean the suction strainer and
ller opening screen when necessary. Automatic
transmission uid is the recommended product.
3. Before changing the hydraulic oil: (a) Lower the
saw head completely; (b) Push the Hydraulic Stop
button; (c) Remove the reservoir drain plug; (d)
Allow the reservoir to drain completely.
System Pressure
1. Hydraulic system pressure is correctly set at the
factory and should not require adjustment for
a considerable period of time. Correct system
pressure is 525 ±25 psi (35.7 ±1.7 bar or 36.9 kg/
cm².)
2. Pressure is adjusted by turning the screw extending
outward from the hydraulic reservoir. Consult
a DoALL service representative if assistance is
needed.
Pump Repair & Replacement
1. DO NOT attempt to repair the hydraulic pump.
Return it to the factory for repair or replacement. Be
sure to specify the correct pump model and serial
numbers when returning the unit.
2. Following a new pump installation: (a) Jog the
Hydraulic Start and Hydraulic Stop buttons
several times; on for two (2) seconds, off for three
(3) seconds until the pump is primed; (b) Check
for proper pump rotation while jogging; (c) Review
wiring connections if the pump rotates in the wrong
direction.
After the pump has been primed, run it
for several minutes while operating the
machine’s controls to purge entrapped air
from the pump and system. Check for oil
leaks while the system is being operated.
Seals & Cups
1. Seals and cups used in DoALL hydraulic systems
are compatible ONLY with hydraulic oils having an
aniline point between 215° and 230° F. (102° and
111° C.).
2. If hydraulic oil having an aniline point not falling
within the above range is used, the seals may either
swell or shrink and harden. This causes machine
malfunction and leakage.

approximately 221° F. (106° C.) will not cause
deterioration of component seals.
COOLANT SYSTEM
1. The machine’s coolant reservoir has a 20 gallon
(75.7 liter) capacity. A reservoir level sight gauge
is located at the machine’s right front side.
2. Check the coolant often for signs of contamination
or breakdown. The reservoir and coolant system
should be drained and cleaned thoroughly when the
cutting uid becomes undesireable for further use.
If another type of coolant is to be used, the entire
coolant system must be ushed (use DoALL’s Kleen
Flush).
3. To thoroughly clean the reservoir section below
the conveyor trough, removal of the trough will be
necessary.
MACHINE CLEANING
1. Keep the machine and its parts as clean as possible
to prevent excessive wear and damage.
2. Use the Flushing Hose as soon as possible to remove
metal chips and other waste materials which may
collect around the saw guides, bandwheels, vises,
slides, sensing arm, etc. The hose has a hand-
operated valve and attaches to the coolant pump.
The DoALL Company recommends using the
Flushing Hose to remove chips at least twice
per each eight (8) hour shift, and more often
with heavier use.
3. Use the supplied shovel-rake to remove accumulated
metal chips or other waste materials from machine
areas. Be sure the band drive motor is stopped
before opening machine doors or covers.
Combination Shovel-Rake.
