Inspect/Tighten or
Replace
Pump/Generator
Belts
Check drive belt and generator belt after the first 24 hours of use, then with each oil change. Tighten or
change belts as needed.
WARNING: Belt slippage can cause static
electricity build-up, which may result in
sparking. Fire ignition can result.
NOTICE: Belt tension and alignment are inter-
related. Do not adjust one without checking the
other.
To tighten belts:
1) Make sure engine is off.
2) Remove belt guard. See Parts Explosion
(Pump, Engine, & Generator)/Belt Guard section of this manual for location.
3) Locate tensioner arm.
4) Using a straight edge make sure the pulleys are aligned
with each other.
5) Loosen rear 1/2" tensioner bolt with 3/4" socket. (Keep
partially torqued to aid in tensioning)
6) Loosen front 1/2" tensioner bolt with 3/4" socket.
7) Using a 1/2" square drive, move the
tensioner plate so notch lines up as shown.
An extension is recommeded for the pump
tensioner.
8) Retighten the front and rear bolts.
NOTE: Proper tensions for pump and
generator belts below are for new belts
only.
9) Replace the belt guard.
DANGER: Do not operate unless the belt guard is in place to prevent access to
rotating parts. Clothing or hair can become rapidly entangled in ungaurded
rotating parts, resulting in serious injury or death.
NOTICE: Some general rules for belt tensions are:
• The ideal tension is the lowest tension without belt
slippage.
• Over tightening decreases belt and bearing life.
• Keep belts clean and free of foreign material that may cause slippage.
Check
Pump
tension
using a
straight
edge.
Belt will
have about
1/4”
deflection
with 10-
12lbs of
force.
Check
Generator
tension
using a
straight
edge.
Belt will
have about
1/4”
deflection
with 5-7lbs
of force.
