Homelite UT10517/18 User Manual

When servicing, use only identical Homelite replacement 
parts.  Use  of  any  other  parts  may  create  a  hazard  or 
cause product damage.

Always wear safety goggles or safety glasses with side 
shields  during  power  tool  operation  or  when  blowing 
dust. If operation is dusty, also wear a dust mask.

Avoid  using  solvents  when  cleaning  plastic  parts.  Most 
plastics are susceptible to damage from various types of 
commercial solvents and may be damaged by their use. Use 
clean cloths to remove dirt, dust, oil, grease, etc.

Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact 
with  plastic  parts.  Chemicals  can  damage,  weaken  or 
destroy  plastic  which  may  result  in  serious  personal 
injury.

All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit 
under  normal  operating  conditions.  Therefore,  no  further 
lubrication is required.

Never  start  the  engine  before  installing  the  guide  bar, 
chain, drivecase cover, and clutch drum. Without all these 
parts in place, the clutch can fly off or explode, exposing 
the user to possible serious injury.

To avoid serious personal injury, read and understand all 
the safety instructions in this section.
