CC4144D Concrete Saw Manual 17
Maintaining the CC4144D
Failure to read and comply with the maintenance
instructions provided in this manual prior to performing
maintenance may result in serious injuries and/or death,
and may harm the saw. DO NOT attempt to perform
maintenance on the saw if you are not properly trained
for it, or are not supervised by an experienced person.
Refer to the Diamond Products’ Parts List for additional
information and part diagrams when performing
maintenance tasks. Refer to the engine manual and
manufacturer as the primary source for all safety,
operations, and maintenance instructions for the engine.
All non-routine maintenance tasks should be performed
by an authorized service center. Contact the saw and/or
engine manufacturers with any additional questions.
Maintenance Overview
Complete the following tasks as required.
DO NOT delay maintenance! Print the
Appendix B
Daily Maintenance Task Chart from the Appendix B to
keep track of maintenance tasks completed.
Daily/Regularly
• Lubricate both blade shaft grease fittings daily.
• Lubricate PTO bearing daily or every 4 hours.
Lubricate PTO shaft splines weekly or every 20
hours.
• Inspect saw for damages.
• Inspect belts for tension and wear. Replace or re-
tension as necessary.
• Tighten loose nuts, screws, and bolts.
• Clean air cleaner (see engine manual).
• Check all fluid levels and fill as necessary (fuel,
engine oil, hydraulic oil, coolant).
• Look for fluid leaks.
• Wipe down and clean saw to remove dust, debris,
and slurry from components (especially fans).
• Check all hoses and lines for damages and/or leaks
and repair as necessary.
Note: Refer to the engine manual and manufacturer for
daily engine care and maintenance tasks.
Part Lubrication
WARNING
• DO NOT grease parts with the
engine running unless stated
otherwise.
Lubricate parts on schedule for maximum efficiency. Use
NLGI No. 2 premium lithium-based grease when
lubricating all parts, EXCEPT the PTO. The PTO
requires high-quality extreme pressure (EP) grease such
as Mobil HTS.
Spray Lubricant
Occasionally lubricate all controls, cables, and linkages
using a spray lubricant when movement becomes stiff
and/or sluggish.
Blade Shaft
Lubricate both blade shaft bearing grease fittings daily.
Grease the fittings with the engine running at idle
(extremely low speed!). Be extremely careful when
greasing the blade shaft with the engine running to avoid
entanglement. Use one to two full pumps of grease
when greasing the blade shaft fittings. Note: If the
bearings are too hot to touch after completing work,
there is either a lack of grease or the belts are too tight.
Front Axle
Lubricate both pillow block bearing grease fittings and
front wheel grease fittings every 40 hours of operation.
Cooling Fan
Lubricate both flange mount bearing grease fittings
every 100 hours of operation.
PTO
Lubricate the PTO bearing daily or every 4 hours of
operation. Lubricate the PTO shaft splines weekly or
every 20 hours of operation.
