Maintenance
•
Being a high performance 2 stroke engine, certain parts of your DA35 can wear quickly. Under normal operation,
pistons, piston rings, needle bearings, spark plugs, etc. may need occasional non-warranty replacement to insure
peak performance.
•
Screws can come loose! After a few flights check that all screws are secure. Periodically check that all screws are
tightened to the correct torque rating. It's recommended to replace, rather than re-use the red aluminum screws.
Spark plug:
Steel prop bolts:
Aluminum crankcase bolts:
Aluminum cylinder base bolts: M5x13mm
Aluminum carb mount bolts:
*Caution: Care must be taken to not over tighten the carb mounting bolts. Over tightening can distort and damage the
injected molded reed valve parts and rubber gaskets.
•
Use a 4mm hex wrench for all M5 cap screws.
•
Use a 3mm hex wrench for all M$ cap screws
•
For spinner mounting, the crankshaft extension is threaded for M5 screws. In this application the 10-32 SAE
screws supplied with most spinners will work fine in the M5 threaded hole. Do not substitute 10-32 screws for any
other screws on the engine!
•
Inspect the engine periodically for any signs of fuel seepage. This can indicate an air leak which can create a lean
fuel/air ratio, which in turn can cause erratic running and engine damage. If tightening the appropriate screws
does not cure the problem, contact Desert Aircraft.
•
After prolonged use, carbon deposits can build up on top of the piston and on the combustion dome of the
cylinder. Great care must be taken when trying to remove these carbon deposits to avoid damaging the parts.
Once an attempt to remove carbon has been made, the task must be completed, as any remaining carbon may
be loosened and can dislodge while the engine is running. This can damage the engine and/or bridge the spark
plug.
