SECTION 1 SAFETY & GENERAL INFORMATION
IMPORTANT! This manual is provided as a supplement to the equip-
ment manufacturer’s manuals. This manual takes into account the
specific use of engines on the Wood-Mizer sawmill. Only safety, main-
tenance, and operating procedures that are not provided by the manu-
facturer are supplied in this manual. Refer to the manufacturer's
manual before attempting to operate this equipment.
This symbol calls your attention to instructions concerning your personal safety. Be sure to observe
and follow these instructions. This symbol accompanies a signal word. The word DANGER indicates
an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARN-
ING suggests a potentially hazardous situation which, if not avoided, could result in death or serious
injury. CAUTION refers to potentially hazardous situations which, if not avoided, may result in minor
or moderate injury to persons or equipment. Read all safety instructions before operating this equip-
ment and observe all safety warnings!
1.1 Motor Operation
DANGER! Always be sure the blade is disengaged and all persons are
out of the path of the blade before starting the engine or motor. Failure
to do so will result in serious injury.
WARNING! Do not for any reason adjust the motor drive belts or belt
support bracket with the motor running. Doing so may result in serious
injury.
WARNING! Remove the blade before performing any motor service.
Failure to do so may result in serious injury.
WARNING! Be sure the power feed switch is in the neutral position
before turning the key switch to the (#1) or (#2) position. This prevents
accidental carriage movement. which may cause serious injury or
death.
1.2 Electrical Operation
DANGER! Make sure all electrical installation, service and/or mainte-
nance work is performed by a qualified electrician and is in accordance
with applicable electrical codes.
DANGER! Hazardous voltage inside the disconnect box, starter box,
and at the electric motor can cause shock, burns, or death. Disconnect
and lock out power supply before servicing! Keep all electrical compo-
nent covers closed and securely fastened during mill operation.

Motor Start
IMPORTANT! When starting the machine for the first time, check that
main motor rotation direction is as indicated by the arrow located on
the motor body (fan guard). If the rotation direction is incorrect, invert
the phases in the phase inverter located in the power socket (electric
box). Setting the phases in the phase inverter correctly will ensure cor-
rect rotation directions of all sawmill motors.
DANGER! Always be sure the blade is disengaged and all persons are
out of the path of the blade before starting the engine or motor. Failure
to do so will result in serious injury.
WARNING! Be sure the power feed switch is in the neutral position
before turning the key switch to the (#1) or (#2) position. This prevents
accidental carriage movement which may cause serious injury or
death.
Turn the key switch to the start (#1) position and press the “START” button on the control panel.
Motor Shutoff
Turn the key switch to the off (#0) position and press the “STOP” button on the control panel.

5-1 EA25doc040611 Brake air gap adjustment
SECTION 5 BRAKE AIR GAP ADJUSTMENT
To ensure proper operation of the brake, it is necessary to set correctly the air gap between
thearmatureandthe electromagnet.Each time the brakeisinstalledor the brake subassemblies are replaced
or the motor overheats or the brake is inspected (the inspection should be performed at least every six
months), check and, if necessary, adjust the brake air gap.
1 - body,
5 - armature,
6 - mounting bolt,
7 - brake casing,
8 - adjustment bolt,
9 - mounting disk,
15 - bearing shield.
Adjustment of the brake air gap is performed when the gap has reached the maximum value (see
Table 1), and always after dismounting the brake and replacing or performing maintenance of damaged sub-
assemblies.

Table 1
To adjust the air gap, perform the following steps :
- Dismount the motor casing,
- Remove the brake casing (7),
- Loosen the mounting bolts (6) half a turn using an adequate allen wrench (see wrench sizes in Table 2),
Table 2
- Screw the adjustment bolts (8) in the electromagnet body one turn using an adequate flat wrench (see
wrench sizes in Table 3),
Table 3
- Place the gap gauge (17) in the gap between the armature (5) and the electromagnet body (1). The
thickness of the gauge should equal the nominal brake gap (see Table 1),
- Using the mounting bolts (6), press the body (1) to the armature so that the gap gauge can be removed
at slight resistance and at the same resistance insert the gap gauge into gaps located every 1200 from the
place of the first measurement,
- Unscrew the adjustment bolts (8) so that they rest on the motor bearing shield or on the face of the brake
mounting disk (9) (in brakes equipped with this element),
- Tighten the brake mounting bolts (6) and check the gap for correct adjustment with the gap gauge.
