d) Screw in Glow Plug
If the glow plug is enclosed separately, it must be screwed into the opening of the cylinder head with a suitable glow
plug key. Do not use any force for this.
Glow plugs wear, especially during the breaking-in stage. If tinder has formed on the glow coil, there may be
problems with starting or operation.
Therefore, we recommend that you always keep some glow plugs at hand for replacement. There are glow
plugs with different heat values (e.g. "cold" or "hot" glow plugs).
Use glow plugs for RC cars only! The wrong glow plug, e.g. for a 4-cycle plane engine, will cause the engine
to run incorrectly and impairs reconciliation.
Generally, the following rule applies: The higher the nitromethane share in the fuel, the "colder" the glow
plug should be. This also applies the higher the ambience temperature when driving.
A "hot" plug must be used at low nitromethane ratios (e.g. for breaking in the motor) or low outdoor tempera-
tures.
e) Oil Air Filter
The air filter of the vehicle is made up of a foam part that is located in a plastic housing with intake opening. The air
filter (the foam part) is already slightly oiled.
The oil in the air filter ensures that finest dust particles stick to the oil and do not get into the motor. These
fine dust particles increase wear at the pistons and cylinder wall and reduce output. At continuous motor
operation without oiled air filter, permanent motor damage may occur; loss of warranty/guarantee!
To remove the air filter from the air filter housing, first
turn out the holding screw (A).
Then turn out screw (B) and take off the air filter lid.
Check the air filter for correct oiling before every run.
Never drive without an oiled air filter!
Oil it with a special air filter oil (not included in the
delivery, available as an accessory).
For oiling, push the air filter (only the foam ring) into a
small plastic bag and add a few drops of air filter oil.
Close the plastic bag and compress the air filter sev
-
eral times so that the air filter oil moistens the entire
air filter.
Reassemble the air filter.
Wash the air filter from time to time (depending on dust load when driving) with benzene or replace it with a
new one. Then oil it as described above.
