SECTION 6: MAINTENANCE

For optimum performance from this machine, this 
maintenance schedule must be strictly followed.

Ongoing
To minimize your risk of injury and maintain proper 
machine operation, shut down the machine imme-
diately if you ever observe any of the items below, 
and fix the problem before continuing operations:

• 

Loose mounting bolts.

• 

Damaged or dull cutter.

• 

Clogged or dirty collet, spindle nut, or spindle 
collet hole.

• 

Blocked dust collection.

• 

Worn or damaged wires.

• 

Low or dirty water in coolant bucket. 

• 

Any other unsafe condition.

Weekly Maintenance
• 

Clean cutter. 

• 

Check/adjust lubrication level in oiler.

• 

Clean/vacuum dust buildup in T-slots.

• 

Inspect spoilboard for defects and flatness.

Monthly Check
• 

Check  tubing  and  connections  for  coolant 
system and oiler system.

• 

Inspect wiring connections for loose wires.

Schedule

To reduce risk of shock or 

accidental startup, always 

disconnect machine from 

power before adjustments, 

maintenance, or service.

Cleaning  the  Model  G0894  is  relatively  easy. 
Vacuum  excess  wood  chips  and  sawdust,  and 
wipe off the remaining dust with a dry cloth.

The  G0894  ball  screw  bearings  require  regular 
lubrication  to  perform  at  their  highest  potential. 
There is an oiler system, located on the back of 
the gantry, that pumps oil to these bearings.

Lubrication

Cleaning & 

Protecting

Lube Type ............T27914 Way Oil or ISO 68 Oil

Lube Amount .........................................1 Pump

Lubrication Frequency ........ 8 hrs. of Operation

Oil Reservoir Max Capacity ....................... 1 qt. 

The  G0894  spindle  motor  requires  a  constant 
flow  of  coolant  to  prevent  overheating.  It  is 
 recommended that distilled water be used to pre-
vent  mineral  buildup  inside  the  system.  Monitor 
water  level  and  cleanliness  regularly.  Replace 
water if discolored or if debris is visible.

If machine is operated or stored in freezing tem-
peratures, anti-freeze should be added to coolant.
