AFTER EVERY TWELVE (12) HOURS OPERATION
Clean Formulation Injection Nozzle
1. Disconnect the Formulation Injection Line (Fig. 10 Ref. 9) at the injection end and then remove
the elbow Ay. (Fig. 10 Ref. 12)
2. Insert a wire through the Coupling (Fig. 10 Ref. 13) into the engine tube to remove carbon
deposits.
3. Then reassemble the Elbow and the Formulation Injection Line.
Check The Fuel Filter
Remove the Fuel Filter (Fig. 16 Ref.5) from the fuel line. If it is dirty, install a replacement and check
the filter within the carburetor (see Carburetion Section).
Clean The Formulation Injection Orifice Assembly
Disconnect the Formulation Injection Line at the FORMULATION INJECTION ORIFICE ASSEMBLY
(Fig.10 Ref. 12.) Clean the injection orifice to remove accumulated residue. Then re-connect the
Formulation Injection Line.
Batteries
No set period of time can be established for the replacement of the "D" size batteries, but the spark
intensity should be checked whenever the machine does not function normally. See the section on
TROUBLE ISOLATION AND CORRECTION concerning the testing of the electronic ignition.
The nominal voltage of fully charged batteries should be at least 12 Volts D.C. This voltage will vary
slightly with battery age and with the ambient temperature conditions. Under some circumstances, it may
vary as much as ± 2 Volts.
WARNING
• IMPROPER USE OF BATTERIES MAY CAUSE LEAKAGE AND EXPLOSION.
THEREFORE, STRICTLY OBSERVE THE FOLLOWING PRECAUTIONS.
(1) INSTALL THE BATTERIES WITH THE POSITIVE (+) AND NEGATIVE (-)
POLARITIES IN THE PROPER DIRECTION.
(2) DO NOT USE NEW AND OLD BATTERIES TOGETHER.
(3) DO NOT USE CYLINDRICAL ALKALINE BATTERIES WITH OTHER
TYPES OF BATTERIES.
(4) NEVER ATTEMPT TO SHORT-CIRCUIT, DISASSEMBLE, OR HEAT
BATTERIES. DO NOT THROW BATTERIES IN FIRE.
• CYLINDRICAL ALKALINE BATTERIES ARE NOT RECHARGEABLE IF RE-
CHARGED, THEY MAY LEAK AND EXPLODE
