If the chain is too tight, the eccentricity of the sprockets
may cause the chain to stretch and/or break.
If the chain is too loose, the starting and stopping of the
machine will shock load the chain, resulting in short
chain life or failure.
A worn or stretched chain will also cause short
sprocket life as the load will not be carried by all of the
teeth on the sprocket, resulting in excessive load on a
few teeth.
To adjust the drive chain:
1. Remove the propulsion chain guard.
2. Unscrew the adjusting screw locknut, but DO NOT
remove it from the screw.
3. Turn the adjusting screw clockwise (CW) to tighten
the chain, or counter-clockwise (CCW) to loosen
the chain.
4. Once the desired tightness has been reached,
tighten the adjusting screw locknut.
5. Drizzle engine oil along the chain and sprockets,
top and bottom.
6. Oil the propulsion chain adjusting nuts.
7. Reinstall the chain guard.
W7. Check Suction Strainer Element
Located on the side of the reservoir, remove and
inspect the filter after the
first 40 hours of operation
and every year thereafter. Clean as required.
To access the filter: See Figure 7-14.
1. Turn off the engine, Make sure the suction valve is
closed (off, CCW).
2. Remove the pin lock (padlock) and pull out the plug
attached to the cable.
3. Use an Allen wrench to turn the screw inside of the
plug housing.
— Turn clockwise to open.
— Turn counterclockwise to close.
4. Remove the six cap screws and lift off the front
cover.
5. Reverse the process to reattach the cover.
NOTE
If for any reason the removal of suction line filter is
necessary, you must seal the hydraulic tank to prevent
external contamination.
