6-5. Cold Weather Starting And Operation
Engine Start
See Operation Section for additional remote panel operating instructions.
1 Prior to starting the engine verify that all fluids (fuel, engine coolant, engine oil, hydraulic oil, and compressor oil) are to the correct level and grade/
specification for the ambient temperature indicated. If the ambient temperature is below 14 ° F ( − 10 ° C) engine coolant block heaters and hydraulic oil
heaters may be be required prior to the engine start. See chart below for minimum heater times.
2 When using the Remote Panel or Crane Remote to start the EnPak, turn unit on and initiate starting sequence. The EnPak control system auto-
matically sets the glow plug time for ambient temperature conditions. See chart below when manually starting the unit from the EnPak service panel.
All external loads on the engine should be off when starting the engine. The air compressor should be off until the engine has been started and
warmed up.
3 Start engine. If engine fails to start after 10 seconds, turn unit off and repeat start sequence.
4 Allow engine to warm up prior to loading engine, See Note 1A. When ambient temperatures are below 50 ° F (10 ° C), the EnPak goes to 2600 RPM
and remains there until the engine has warmed to 100 ° F (38 ° C).
Be sure to warm up engine, not only in the winter, but also in warmer seasons. An insufficiently warmed − up engine can shorten its service life.

Normal stabilized engine coolant temperatures should be in the range of 160 − 220 ° F (71 − 104 ° C). In extreme cold conditions it may become neces-
sary to block a portion of intake cooling air. See Engine Troubleshooting Section for trouble shooting over or under coolant temperature.

Glow plugs are automatically activated when the unit is turned on from the EnPak remote or crane remote. Times listed are the maximum recom-
mended glow plug times when starting the EnPak using the manual service panel. Extending the glow plug times beyond those listed can cause
damage to the glow plugs and system.

For additional engine oil specification see Engine Maintenance Label or Engine Operators Manual.
3 Times listed are for the standard Miller Part No. 242954, Engine Block Heater, 120V.
4 Maximum start − up viscosity limited to 2100cSt, minimum intermittent viscosity limited to 6cSt. Use of a high viscosity index (VI) fluid is recommen-
ded to attain the ISO fluid recommendations listed. Refer to EnPak Technical Bulletin for further details. Never allow fluid temperatures to exceed
160

5 Optional, Miler Part No. 300546, Hydraulic Reservoir Oil Heater. Necessitated only when oil exceeds maximum start − up viscosity of 2100cSt.”
− Not required.
