3 Use proper rated and length extension cord, see Engine Operator's manual
1 Cooling air flow restricted to engine 1 Remove air flow restrictions from engine
2 Low oil level 2
Check oil level on dipstick. If oil is not visible on dipstick, check oil level using LOWER fill plug BEFORE
adding oil. Oil should be visible and to the top 2 threads of LOWER fill plug (not the dipstick tube). Do not
over fill with oil, see Engine Operator's manual for more information. Note: Only use 5W-30, 4-stroke
automotive detergent oil with an API SERVICE rating of SJ or higher. Engine oil capacity [LCT 208cc
engine] - 16 oz. (0.473 liter). The use of automotive synthetic oil is acceptable.
Engine Systems - Note: For all engine problems, see the Engine Operator's manual for additional troubleshooting information and engine manufacturer contact information.
WARNING - Before attempting to make any inspections, repairs or adjustments, stop the engine, wait for all moving parts to stop moving and carefully disconnect the engine spark plug wire. If tipping or
turning the snow blower is required for any inspection or repair, first wait until the engine is cool to the touch and then drain the engine of all fuel and oil into suitable containers and store or dispose of in a
proper manner.

Release drive control handle then pull machine backward to try and unlock axle. If axle will not unlock,
check to ensure drive friction plate is not engaged to drive friction wheel, also check axle drive gear, axle
and bushings for damage or binding.
6 Wheel to axle pins broken or missing 6 Replace pins attaching wheels to axle
1

11
Snow too heavy or wet or has other material
in it
11
Depending on ambient temperature, humidity levels, and overall climate conditions including actual snow
conditions, there may be no solution as snow may be too wet or compacted to move or throw. If snow is
filled with foreign material, damage to the snow thrower may result. Avoid snow with foreign materials.
12
Forward speed too fast while blowing snow,
overload
12 Slow and reduce snow ingestion, allow engine to maintain it’s maximum rpm.
13
Engine not running at rated speed under
load
13
Have engine inspected and RPM tested under load to ensure engine is operating at the recommended
RPM. Check for machine mechanical binding causing engine to not run at rated RPM.
