John Deere Products & Services Portable Generator DCA70SSJU4i User Manual

Before connecting this generator to any 

building’s electrical system, a 

electrician must install an isolation 

(transfer)  switch. Serious damage to 

the building’s electrical system may occur 

without this transfer switch.

When connecting the generator to a isolation (transfer) 

switch, 

alWaYs have power applied to the generator’s 

internal battery charger. This will ensure that the engine 

will not fail due to a dead battery.

When the generator is set in the 

aUTO mode, the 

generator will 

automatically start in the event of 

commercial power falling below a prescribed level 

by means of a contact closure that is generated 

automatically by a transfer switch.

When running the generator in the 

aUTO mode, 

remember the generator can start up at any time without 

warning. 

never attempt to perform any maintenance 

when the generator is in the auto mode.

The engine speed switch 

must be set to the “High” 

position when running in the 

auto-start mode. Failing 

to set the switch in the proper position can result in 

damage to your generator when it turns on.

When the 

Auto Off/Reset Manual switch is placed 

in the 

aUTO position, the engine glow plugs will be 

warmed and the engine will start automatically.

When starting generator in 

aUTO mode use the “Manual 

Start-up” procedure except where noted (see below).
1.  Perform steps 1 through 5 in the Before Starting section 

as outlined in the Manual Starting Procedure.

2.  Place the 

auto off/reset manual switch (Figure 53) 

in the 

aUTO position.

3.  Continue operating the generator as outlined in the 

Manual Start-up procedure (start at step 3).
