OR EXTENSION CORD BEFORE PERFORMING
ANY MAINTENANCE TO THE FLOOR PLANER.
RECONNECT THE SPARK PLUG BEFORE
RESTARTING THE ENGINE. IF ELECTRIC MOTOR
EQUIPPED, TURN THE ON/OFF SWITCH TO THE
OFF POSITION BEFORE RECONNECTING THE
EXTENSION CORD. IMPROPER PROCEDURES
CAN RESULT IN PROPERTY DAMAGE AND/OR
PERSONAL INJURY.
CHECKING V-BELT TENSION AND ALIGNMENT.
Application: All Models.
Proper V-belt tension and alignment are essential for
smooth transmission of horsepower and extended
service life. Improper tension and alignment will
accelerate V-belt wear and contribute to decreased
productivity. The V-belt is tensioned at the factory with
the maximum recommended tension force. Check the
belt tension at least two times during the first day of
operation, as there will normally be a rapid decrease in
belt tension until the belt has run in. Check the belt
tension every eight hours of operation thereafter and
maintain tension within the recommended range.
The correct operating tension for a V-belt drive is the
lowest tension at which the belt will not slip under peak
load conditions.
Tools Required:
1 each, 16 inch minimum length straightedge.
1 each, 10 lbs minimum capacity, tension scale or belt
tension tool.
1) If the Floor Planer is powered by an engine,
disconnect the spark plug wire. If powered by an
electric motor, disconnect the extension cord or Floor
Planer from the power source.
2) Position the Floor Planer on a suitable work bench
with the V-belt approximately at waist level.
3) Using the 9/16 inch wrench, remove the belt guard
from the main frame. Clean the inside of the belt guard
with an appropriate solvent. Check for signs of wear
and damage.
CAUTION
Observe all applicable safety precautions for the
solvent.
4) Check belt tension using the spring scale or belt
tension tool midway between the engine and
driveshaft pulleys. Belt deflection should measure
approximately 3/16 inch at 3-7/8 to 5-1/2 lbs force.
FIGURE 32. If tension is within specifications, proceed
to Step 4. If tension is not within specifications, refer
to INSTALLING A REPLACEMENT V-BELT for
specific information.
FIGURE 32
5) Belt alignment is checked with the straightedge.
Place the straightedge squarely against the driveshaft
pulley. Properly aligned pulleys should also place the
straightedge squarely against the engine pulley.
FIGURE 33. Remove the straightedge and rotate the
engine pulley 120 degrees. Recheck alignment with
the straightedge. Repeat the process until the engine
pulley is rotated a full 360 degrees. Maximum
allowable misalignment is +- 1/32 inch. If pulley
alignment is not within specifications, refer to
INSTALLING A REPLACEMENT V-BELT for specific
information.
6). Install the belt guard to the main frame. Install the
flat washers and self-locking hexagon nuts. Torque the
nuts to 35 ft lbs (47 N.m). Determine that all safety
related decals affixed to the belt guard are fully
readable. If any decal is not fully readable, replace
with a factory approved, replacement part only.
7) If the Floor Planer is powered by an engine,
reconnect the engine spark plug wire. If powered by
an electric motor and the machine is to be used
immediately, reconnect the extension cord or Floor
Planer to the power source. Determine that the
ON/OFF switch located on the operator handle is in
the OFF position.
DANGER
UNEXPECTED MACHINE START UP CAN RESULT
IN PROPERTY DAMAGE AND/OR PERSONAL
INJURY.
