Tips On Cold Weather Starting; Preparation For Storage - Hobart 60CU24 Operation And Maintenance Manual With Illustrated Parts List

OM-2098C / Operation and Maintenance Manual
60CU24 / Series 500060C / 400 Hz. Generator Set
To install AC output cables proceed as follows:
(1) Open control box door of the generator set and remove the lower panel.
(2) Remove Plexiglas cover in front of the power module assembly.
(3) Remove the cover panel on the cable tray covering the cable clamps.
(4) Loosen screws on cable clamps.
(5) Route cables through cable clamps, and up to the load side of the load contactor(s).
(6) Connect the phase cable terminal lugs to the appropriate terminal studs on the contactor(s): cable
lug "A" to terminal stud "A", "B" to "B", and "C" to "C".
(7) Connect the cable's neutral terminal lug securely to the neutral (ground) stud on the power
module assembly.
(8) Connect the "E" and "F" cables to the "E" and "F" studs on the power module assembly.
(9) Tighten clamp screws securely, but avoid damage to cable insulation.
(10) Replace Plexiglas cover panel, lower panel, and close canopy door.

2) Tips on Cold Weather Starting

a) Battery and Cables
To start in cold weather, a diesel engine must crank at a fairly high speed. A worn out battery,
partially discharged battery, and poor or loose cable connections will reduce cranking speed. Battery,
cables and connections should be cleaned and tightened regularly.
b) Fuel
For an engine to start and continue running, fuel must flow through the injection system. Unblended
#2 diesel fuel "clouds", forming filter –clogging waste at temperature around +15° F (-10° C) making
starting and running impossible. Most engine manufactures recommend that fuel have a cloud point
at least 10° F (5° C) below the coldest anticipated temperature.
c) Lube Oil
Engine lubricating oil gets thicker at lower temperatures. Many oils that flow freely at 70º F (21º C)
are extremely thick at 0º F (-18º C). Follow your engine manufacturer's recommendations regarding
oil viscosity for the coldest temperatures you expect your engine to encounter.

3) Preparation for Storage

When a generator set is to be stored or removed from operation, special precautions should be taken to
protect the internal and external parts from rust, corrosion, and gumming in the engine fuel system.
