Figure 6 - 9: Metering Roller Cleaning
Keep the hopper clean and free of debris to
ensure trouble-free operation. Do not leave
product in the hopper overnight or longer as
condensation may cause the product to cake
up. Clean the hopper as follows:
1. Follow the instructions in the preceding
section to remove the metering rollers
2. Open the shut-off plate to allow material to
flow into the collection container(s).
3. Clean the hopper and bottom thoroughly.
4. Place the product in a sealed container and
store indoors.
Lubrication
Bearings
There are two types of bearings used on the
applicator. They are:
a) Sealed bearings which require no
relubrication.
b) Greasable flange bearings (2) on the clutch
shaft (1997 models and older). Apply two
shots of multi-purpose grease to each
bearing daily.
Chain drives
Lubricate with a recommended chain lubricant.
Grease or heavy oil will attract dirt and dust.
Metering Gearbox
Lubricant all moving parts of the metering gear
box with a “cleaner lubricant” such as
penetration oil. Grease or heavy oil will attract
dirt and dust causing premature wear and
difficult shifting.
Belt and Chain Adjustments
Proper V-belt and chain tension is critical to the
efficient function and long wear of all drive
systems. Belts and chains that are too tight, too
slack or misaligned will wear prematurely.
Alignment
Periodically check the alignment of all pulleys
and sprockets. Place a straight edge against
them to see if belts and chains are in line and
shafts are parallel. Turn the pulley or sprocket
and check at different points for warping.
Replace any damaged parts.
Fan Drive Belt (Fig. 6-10 thru 6-12)
The correct fan belt tension is ½ inch of
deflection when a 5 pound force is applied at
the mid-point of the belt span.
