Do not run an engine in an enclosed area without adequate ventilation. · Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area. · Allow fresh outside air into the work area to clear the exhaust fumes out. |
Engine Oil
Use oil viscosity based on the expected air temperature range during the period between oil changes.
The following John Deere oils are preferred:
MX4888
· TURF-GARD®
· PLUS-4®
Other oils may be used if above John Deere oils are not available, provided they meet the following specification:
· API Service Classification SG or higher
Checking Engine Oil Level
