and always ensure that the ignition is turned off when priming, choking, changing
propellers or storing.
Warranty
The true spirit of the JC Engines warranty endeavours to fairly resolve any matters
that impact on the proper operation or performance of the engine and ignition system,
as may result from defective materials or workmanship from the manufacturer. This
intent may be compromised by the very nature of the application of model airplane
engines, whereby various forms of harm are possible that are not related to defective
workmanship and /or materials on the part of the manufacturer. This would include
crash damage, incorrect fuel/ lubricant or mix ratio; incorrect mixture settings;
incorrect propeller selection, inadequate cooling, incorrect voltages for the ignition,
etc.
Disassembly and /or modifications to the engine or ignition system will void the
warranty.
The warranty does not cover damage resulting from a mishap, or damage caused by
incorrect operation of the product in terms of the operating instructions, or shipping
costs associated with any warranty service.
Mounting the Engine
Whereas the threads in the engine stand-offs and prop driver are perfectly adequate
for the purpose, they are easily damaged by excessive tightening or by cross threading.
Take care when starting the bolts to ensure that they engage the threads properly and
make use of a suitable thread lock rather than applying excessive torque.
LOCTITE 242 Blue or an equivalent thread lock is preferred. Be aware that
products such as LOCTITE RED 262; 272; 277 are considered permanent and require
specl treatment to remove.ial
Propeller bolts should be applied without thread lock as they should be re-tightened or
checked regularly. Similarly, bolts passing through a wooden firewall should be
checked regularly.
JC Engines are not sensitive to orientation and can thus be mounted in the position
best suited to the particular installation, cowl shape, fuel tank location, etc.
