SECTION 6: MAINTENANCE

Always disconnect power 

to  the  machine  before 

performing maintenance. 

Failure  to  do  this  may 

result in serious person-

al injury.

For  optimum  performance  from  your  machine, 
follow this maintenance schedule and refer to any 
specific instructions given in this section.

Daily Check:

• 

Loose mounting bolts.

 

Worn or damaged wires.

 

Worn switch

 

Any other unsafe condition.

Monthly Check:

• 

Belt tension, damage, or wear.

• 

Clean/vacuum dust buildup off of motor.

Schedule

Cleaning  the  Model  H8259  is  relatively  easy. 
Vacuum  excess  wood  chips  and  sawdust,  and 
wipe off the remaining dust with a dry cloth. If any 
resin has built up, use a resin dissolving cleaner 
to remove it. Treat all unpainted cast iron and steel 
with a non-staining lubricant after cleaning.

Cleaning

Protect  the  unpainted  cast  iron  surfaces  on  the 
lathe by wiping them clean after every use—this 
ensures moisture from wood dust does not remain 
on bare metal surfaces.

Keep  the  bed  rust-free  with  regular  applications 
of products like G96

®

 Gun Treatment, SLIPIT

®

, or 

Boeshield

®

 T-9.

Unpainted Cast Iron

Lubricate the locations shown in
