Thank you for choosing an SH .12 Pro Rear-Exhaust engine. All SH
engines are designed for high power output and easy handling. The
SH .12 Pro Rear-Exhaust engines are designed specifically for 1/10th
scale trucks and sedans, and feature dual ball bearing-supported
crankshaft, ABC piston and sleeve, two-needle carburetor, pull-start
assembly (where applicable), heat-dissipating cylinder head and
superb attention to detail and quality. All SH engines are manufactured
using CNC manufacturing equipment to ensure every engine is
produced to the exacting quality that you have come to expect from
an engine of this caliber.
SH engines will consistently give you dependable performance and
reliability and will be a source of satisfaction and pleasure if you
follow these instructions as to the engine’s proper and safe use.
You alone are responsible for the safe operation of your engine, so
act sensibly and with care at all times. This engine is not a toy. It is
a precision-built machine whose power is capable of causing
serious injury to yourself and others if abused, misused or if you fail
to observe proper safety precautions while using it.
☞
Never use any fuel in your engine other than glow fuels
specifically designed for use in model car/buggy engines. Use of
any other types of fuel can cause severe damage to the engine and/or
personal injury.
NEVER USE GASOLINE OR DIESEL FUEL!
☞
Never operate your model on any public streets. This could
cause traffic accidents, personal injury or property damage.
☞
Glow fuel engines emit exhaust vapors that are poisonous and
can be dangerous to your health. It is important that you operate
your engine in a very well-ventilated area, preferably outdoors.
☞
Before starting the engine, make sure that the throttle trim is set
to the idle position. Starting the engine at any setting above idle can
cause the model to lurch out of your hands.
☞
When the engine is running, there are certain parts that rotate
at high speeds. Be careful not to touch the drive shafts, gears, clutch
assembly or any other moving parts. Serious injury could result.
☞
It is normal for the engine to get very hot during operation,
especially the cylinder head and exhaust system. Never touch
the engine or exhaust system while they are hot.
☞
Model car engines produce vibration when they are running.
It is important to periodically check the engine mounting screws,
exhaust mounting screws and other assemblies to ensure they
are tight. Running the engine with the engine mounting screws
loose can lead to severe engine and/or chassis damage.
