Inspections and Maintenance
5.1
Visual inspection
First inspect the system for proper connections (Fig. 3).
5.2
Tightness and contamination
High-pressure hydraulic hoses and all couplings,
nipples, fittings and connections must be checked
for damage and possibly replaced or cleaned.
Contamination in the hydraulic system will cause
malfunctions and operating failure. Check hydraulic
components for tightness. Defective components
must be professionally replaced.
5.3
Inspection of pressure gauge
To ensure the torque precision, inspect the
electronic and the precision of the gauge (Fig. 4,
item 1) by testing the gauge. This inspection must
be performed at least once a year.
In case of damage, authorized personnel must im-
mediately inspect the alkitronic® NOVA Hydraulic
Power Unit for electrical safety and mechanical de-
fects. Otherwise a mechanical and electrical safety
inspection is recommended once a year.
5.4
Expert inspection
According to legal regulations a mechanical and electrical
safety inspection once a year is required.
For safety reasons all hydraulic hoses used for
regular requirements must be replaced at the
latest after five years (additional max. two years
storage). For increased requirements (multiple shift
operation, short cycle times, hand tools) replace
the hoses after two years.
Hydraulic hoses should be stored in cool, dry,
free from dust conditions. Avoid direct sunlight,
UV-radiation and storing temperatures below
-10°C (+14°F). Hose ends and connections must
be sealed.

Maintenance
Before starting any maintenance work, the
alkitronic® NOVA Hydraulic Power Unit must be
disconnected from the power supply (pull power
cord plug).
Repairs may only be performed by authorized
personnel.
The Hydraulic Power Unit does not require any special main-
tenance. However, the oil level in the tank must be checked
regularly.
By frequent use of the alkitronic® NOVA Hydraulic Power Unit
a yearly oil change is recommended. For proper oil type refer
to section 1 "Technical information".
6.1
Checking oil level
Place the Hydraulic Power
Unit horizontally on level
ground. Remove dipstick (1)
und clean it with a lint-free
cloth. Screw the dipstick in
again. After renewed un-
screwing, check if the oil
level is within the recom-
mended range. Use the two
markings max and min. If
the oil level is within the
range of max and min, the
level is fine. If the level is
below min, add oil (Fig. 6).
6.2
Adding oil
Place a funnel in the oil filler
spout (1) and add a suffi-
cient quantity of hydraulic
oil "HLP 46".
Clean the housing of oil.
Cleaning material and oil
residue must be properly
disposed of (Fig. 7).
Install dipstick (1) in clock-
wise direction (Fig. 7).
6.3
Draining Oil
For draining, place an approx. 5 cm (2 in)high wooden block
(1), or similar, beneath the vent-side of the Hydraulic Power
Unit, so that the oil in the unit will flow towards the lowest
point.Collect leaking oil by placing a drain pan (2) underneath.
Open and remove oil drain plug (3) by turning it counter-
clockwise with an 8 mm hex head wrench. To speed-up the
