There are tools that the technician can use in order to define the problem, such as:
1.
Interview the customer.
•
Get a good description of their complaint.
•
If it is an intermittent problem, verify what conditions aggravates the problem as best as possible.
•
Get an accurate service history of the equipment.
•
Find out how the customer uses and stores the equipment.
2.
Direct observation:
•
Do not take it that the customer is correct with their description of the problem. Try to duplicate the prob-
lem.
•
Check the general condition of the equipment (visually).
I.
Cleanliness of the equipment will indicate the level of care the equipment has received.
II.
Make sure the engine and attachments are securely fastened.
III.
The tune-up factors.
NOTE: Most hard starting and poor running conditions can be solved by preforming a tune-up.
a. Check the condition and amount of oil in the crankcase.
b. Check the level and condition of the fuel.
c. Check the air filter and look for signs of dirt ingestion.
d. Check the ignition and “read” the spark plug.
e. Look for obvious signs of physical damage, bent blade, exhaust system blockage or cooling sys-
tem blockage.
6.
Broken starter rope.
•
Usually means the engine was hard to start.
•
Makes it impossible to confirm any running or hard starting symptoms by direct observation.
•
Some inference can be made from checking other factors of the general condition of the equipment.
