3.
Push the idle-side blade wheel/shaft housing all the way in to collapse the rear tensioner
piston.
4.
Pull the idle-side blade wheel/shaft housing away from the tensioner.
There are two fill plugs provided on the tensioner. For easiest access, it is recommended
to use the hole behind the gauge to refill the tensioner.
5.
Clean any dirt and debris from the plug area.
6.
Use a 7/16” wrench to remove the plug, making sure to keep the plug o-ring with the plug.
7.
Use a small funnel, cup or squirt can to add hydraulic fluid through the fill plug hole until a
puddle of fluid forms and is maintained over the fill hole.
8.
As you maintain the puddle, manually extend the rear piston as far as it will travel.
IMPORTANT!
Use care not to draw air into the tensioner. Use pliers to
pull the rear piston if necessary, but only grip the outer 1/4” (6mm) of
the rear piston. Gripping or marring the surface beyond this point could
result in seal damage and prevent the system from holding tension.
9.
Reinsert the plug and thread 2-3 turns.
10.
Turn the tension handle clockwise until 6 or 7 threads show beyond the front piston block.
11.
Tighten the plug all the way.
12.
Push the idle-side blade wheel/shaft housing all the way in to collapse the rear tensioner
piston.
NOTE:
If the piston does not extend at least 2” from the end of the ten-
sioner block, repeat Steps 1-11.
13.
Reinstall the blade and blade housing covers.
If you have trouble installing a blade, it may be necessary to remove some fluid. Open the
plug one turn and turn the tension handle in until some fluid is pushed out. Tighten the
plug and retry.
