Safe Operation
Efficient and safe operation of the Valmar
Pneumatic Applicator requires that each
operator reads and understands the operating
procedures and all related safety precautions
outlined in this section. A pre-operation
checklist is provided. It is important for both
personal safety and maintaining the good
mechanical condition of the Applicator, that this
checklist is followed.
Pre-Operation Checklist
Before operating the applicator and each time
thereafter, check off the fallowing areas:
1. Check the implement and applicator
hydraulic system. Ensure that the
hydraulic reservoir in the tractor is filled
to the required specifications.
2. Inspect all hydraulic lines, hoses, fittings
and couplers. Use a clean cloth to wipe
any accumulating dirt from the couplers
before connection to the tractor’s
hydraulic system.
3. Inspect all delivery hoses for any wear
and restrictions. Repair or replace if
necessary.
4. Inspect the hopper for accumulation of
any foreign material that could plug the
venture system.
5. Check all the chains, sprockets, belts
and pulleys for proper adjustment and
tension. Adjust as shown in the
Adjustment and Service section of
manual.
6. Check the fan and manifold for any
accumulation of straw of dirt. Clean as
required. Run the fan at field speed to
clear hoses and outlets of foreign
material.
7. Check the metering rollers. They must
turn easily. Worn rollers will alter rates.
8. Ensure that all bearings turn freely.
9. Inspect the gearbox for alignment and
proper lubrication. Refer to Adjustment
and Service section of manual.
10. Operate the electrical clutches for proper
engagement. Refer to Adjustment and
Service if clutches do not work properly.
11. Make sure that all guards and shield are
in place.
12. Check the ground drive tire pressure.
Inflate to 30 psi.
13. Check mounting hardware for hopper to
implement. Tighten where necessary.
Control Unit (Figure 4-2)
The applicator is equipped with an electrically
operated control unit. The unit allows selection
of left, right or both metering rollers as well as
normal or alternate rates of product application.
The control unit also indicates incorrect
manifold pressures. Refer to Assembly and
Installation Manual for control unit installation.
Power Switch
Push the power switch to “ON” position for
operation of control unit. A light above the
switch indicates power is on.
Selector Switch
Select BOTH for the operation of both metering
rollers for full width application of product.
Select LEFT or RIGHT when only half the
application width is desired. This is useful when
finishing a field or where overlapping may occur.
Green lights above the dial indicate which
option is selected.
Normal/Alternate Rate (Optional)
If an alternate rate kit is installed, either a
NORMAL rate or an ALT (alternate) rate can be
selected and switched from one to the other at
any time. The desired alternate rate must be
determined when purchasing the kit according
to the following chart:
Alternate Rate Sprockets

14 30% Lower
16 20% Lower
18 10% Lower
