GMC 1986 P-Truck Service Manual page 3

To reduce the chance of personal injury and/or property damage, the follow­
ing instructions must be carefully observed.
Proper service and repair are important to the safety of the service techni­
cian and the safe, reliable operation of all motor vehicles. If part replacement
is necessary, the part must be replaced with one of the same part number or
with an equivalent part. Do not use a replacement part of lesser quality.
The service procedures recommended and described in this service
manual are effective methods of performing service and repair. Some of these
procedures require the use of tools specially designed for the purpose.
Accordingly, anyone who intends to use a replacement part, service proce­
dure or tool, which is not recommended by the vehicle manufacturer, must
first determine that neither his safety nor the safe operation of the vehicle will
be jeopardized by the replacement part, service procedure or tool selected.
It is important to note that this manual contains various Cautions and No­
tices that must be carefully observed in order to reduce the risk of personal
injury during service or repair, or the possibility that improper service or repair
may damage the vehicle or render it unsafe. It is also important to understand
that these 'Cautions' and 'Notices' are not exhaustive, because it is impossi­
ble to warn of all the possible hazardous consequences that might result from
failure to follow these instructions.
