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. 

 

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.

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. 
 

 

 
UNEXPECTED MACHINE START UP CAN RESULT 
IN PROPERTY DAMAGE AND/OR PERSONAL 
INJURY.
