Check Coolant Level; Check And Adjust Fan Belt Tension - Hitachi ZAXIS 17U-2 Operator's Manual

Check Coolant Level --- daily
Check that the coolant level is between the FULL and
LOW marks on coolant reservoir (2). If the coolant level
is below the low mark, remove the reservoir cap (1) and
add coolant to coolant reservoir (2).
WARNING: Do not loosen radiator filler cap (1)
unless the system is cool. Hot steam may escape,
possibly causing severe burns. Loosen the cap
slowly to the stop after the coolant becomes cool.
Release all pressure before removing the cap.
If coolant reservoir (2) is empty, add coolant through
radiator cap (1).

Check and Adjust Fan Belt Tension

--- every 100 hours (first time after 50 hours)
IMPORTANT: Loose fan belt tension may result in
insufficient battery charging, engine
overheating as well as a rapid, abnormal
belt wear. Belts that are too tight,
however, can damage both water pump
and alternator bearings, and belts.
Check:
Check fan belt tension by depressing the fan belt
mid-point with the force [approx. 98 N (10kgf, 22 lbf)] of
thumb. Deflection must be 7 to 9 mm at a mid point
between fan pulley (1) and alternator (2).
In addition, check the fan belt for any damage. If the belt
has any cracks, replace the belt with a new one.
