to provide improved viewing of the particular components being discussed. This is for
informational purposes only -- never operate the Articulator with any of the safety
covers removed!
Safety is a primary concern in the design and manufacture of all LasTec products. Unfor-
tunately, our extensive efforts to provide safe equipment can be negated by a single care-
less act of an operator. In addition to the design and configuration of the Articulator,
hazard control and accident prevention are also dependent upon the awareness, con-
cern, prudence and proper training of all personnel involved in the operation, transporta-
tion, maintenance, and storage of the Articulator. The Best Safety Device is an
informed, careful Operator! We ask you to be that kind of operator.
NEVER operate the Articulator with any safety covers removed!!
Work safely! Follow all safety rules! A careful operator is the best
insurance against accidents!

3-2 325EFK/Odoc061600 Initial Set-Up
3.3 Deck Drive Belts
The deck drive belts are located between the gearbox and the center mower deck, under
the center deck belt cover. To access the belts, remove the wing bolt and lift the cover
from the deck.
The spring-loaded idler system automatically tensions the belts to the proper level.
Check the belts for visible wear or damage. If either belt appears excessively worn, dam-
aged, cracked, weathered, or otherwise appears to pose an unsuitable or unsafe operat-
ing condition, replace the belt.
Check the belts for proper tension. If the idler arm pivots to its maximum stroke without
adequately tightening the belts, you need to replace the belts. If the belts you are check-
ing are new, and the idler tensioner goes to its maximum stroke without adequately tight-
ening the belts, it is likely you have installed the wrong size belts. Contact your LasTec
dealer for the proper belt lengths for your Articulator.
If you are unable to install new belts with the idler arm at its minimum stroke, it is likely
you are installing the wrong size belts. Contact your LasTec dealer for proper belt
lengths for your Articulator.
Be sure that the idler tensioning spring is properly installed and in good condition. If for
some reason this spring becomes loose, detached, or fatigued, the idler will not properly
tension the belts.
Clean entire deck area (under the belt cover) of all excess grease, oil, fuel, grass, or
debris before operating the Articulator. This will help prevent damage to the equipment,
fire hazard, and projectile hazards.
Be sure to replace the belt cover and hardware.
NEVER inspect, adjust, or change the deck drive belt while the engine
is running!
ALWAYS clean the entire deck(including under the belt cover) of all
grease, oil, fuel, grass, or debris to prevent fire & projectile hazards!

3.4 Deck Belts
The deck belts are located under the belt covers on each deck. To access each belt,
remove the wing bolts, wing nuts and washers, and lift the belt cover from the mower
deck.
The double-pulley idler belt tensioning system automatically tensions the belts on the
mower decks, thus eliminating the need for manual belt tension adjustment.
Check the belts for visible wear or damage. If any belt appears excessively worn, dam-
aged, cracked, weathered, or otherwise appears to pose an unsuitable or unsafe operat-
ing condition, replace the belt.
Check the belts for proper tension. If an idler arm pivots to its maximum stroke without
adequately tightening the belt, you need to replace the belt. If the belt you are checking is
new, and the idler arm pivots to its maximum stroke without adequately tightening the
belt, it is likely you have installed the wrong size belt. Contact your LasTec dealer for the
proper belt lengths for your Articulator.
If you are unable to install a new belt with the idler arm at its minimum stroke, it is likely
you are installing the wrong size belt. Contact your LasTec dealer for proper belt lengths
for your Articulator.
Be sure that each idler pulley tensioning spring is properly installed and in good condition.
If for some reason this spring becomes loose, detached, or fatigued, the idler will not
properly tension the belt.
Clean each entire deck area (under the belt covers) of all excess grease, oil, fuel, grass,
or debris before operating the Articulator. This will help prevent damage to the equip-
ment, fire hazard, and projectile hazards.
Be sure to replace all belt covers and hardware.
NEVER inspect, adjust, or change the deck belts while the engine is
running!
ALWAYS clean each entire deck (including under the belt covers) of
all grease, oil, fuel, grass, or debris to prevent fire & projectile
hazards!
