LPW / LPWS / LPWX ENGINE OPERATORS' HANDBOOK
INTRODUCTION
This handbook explains the operation
and routine maintenance of Lister Petter
water cooled diesel engines in the Alpha
(LPW, LPWX) and New Alpha (LPWS)
series.
Please note that If your engine is part
of a generating set, there is a separate
operators' handbook for the genset,
to explain such features as the control
module.
ENGINE IDENTIFICATION
To identify which model of Lister Petter
LPWX/LPW(S) diesel engine you are
using refer to the engine serial number,
which is stamped on a plate attached to
the engine. It identifi es the type and build
of the engine (see table below) to enable
the correct maintenance procedures to
be carried out. Here is a sample serial
number:
06 001234 LPWS3 A 402
06........................Year code (06 = 2006)
001234...............Unique engine number
LPWS3 ............................Engine model
A .........................Anti clockwise rotation
402....................................Build number
The illustrations on page 4 show features
of the different engine models. When
following the instructions in this handbook
you will need to be familiar with the parts
labelled.
USING THIS HANDBOOK
Operating or servicing a diesel engine
is potentially dangerous. You must not
