inclusive. other subject areas can be added at the
discretion of the owner(s) and/or operator(s):
1) Check all fasteners for proper torque values. If a
fastener requires retorquing, consult a torque chart for
proper value. Properly discard and replace any worn
fastener with a factory approved, replacement part.
2) Check the v-belt for wear. Adjust or replace
as necessary. Check pulleys for wear and proper
alignment. Many loose materials created as a result of
the operating processes can be extremely abrasive.
3) Keep the Surface Planer clean. Wash the unit after
each use. Keep loose material from accumulating
around engine cooling fins. Determine that the interior
sections of the frame are free of material build-ups.
Such build-ups can restrict the operating process and
present a potential safety hazard. Clean and remove
any material build-up from the Surface Planer after
each use.
4) Engine service life can be extended with proper air
cleaner maintenance. Consult the material supplied by
the engine manufacturer for specific information.
5) Check for proper engine oil level. Always use clean,
high quality engine oil. Change oil as required. Consult
the material supplied by the engine manufacturer for
specific information.
DO NOT PERFORM PREVENTATIVE
MAINTENANCE CHECKS WITH THE ENGINE OR
ELECTRIC MOTOR RUNNING. STOP THE POWER
SOURCE AND DISCONNECT THE SPARK PLUG
OR EXTENSION CORD BEFORE PERFORMING
ANY MAINTENANCE TO THE SURFACE 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: SP684 SURFACE SHARK
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, 9/16 inch wrench
1 each, 16 inch minimum length straightedge
1 each, 10 lbs minimum capacity, tension scale or
belt tension tool
1) If the Surface Planer is powered by an engine,
disconnect the spark plug wire. If powered by an
electric motor, disconnect the extension cord or Surface
Planer from the power source.
2) Position the Surface 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.
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 28. If tension is within specifications, proceed
to Step 5. If tension is not within specifications,
refer to INSTALLING A REPLACEMENT V-BELT
OR PULLEY for specific information.
