Engine Oil; Battery - Ford F-650 2011 Supplement Manual

CHANGING THE WIPER BLADES
1. Pull the wiper arm away from the
vehicle. Pry open the lock cover
with your thumb (1) to release the
blade and pull the wiper blade down
toward the windshield to remove it
from the arm (2).
2. Insert the wiper arm hook into
the wiper arm (3).
Replace wiper blades at least once
per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield. Refer to Windows and wiper blades in the Cleaning
chapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.

ENGINE OIL

Refer to your engine operator's manual for information on checking and
adding engine oil as well as engine oil specifications, capacities and
required maintenance.

BATTERY

Your vehicle is equipped with two or three maintenance-free batteries
which are mounted in a covered tray and located on the left frame rail.
The covered battery tray, depending upon application, may also have one
or two steps attached.
WARNING: This vehicle is equipped with more than one
battery, removal of cable from only one battery does not
disconnect the vehicle electrical system. Be sure to disconnect cables
from all batteries when disconnecting power. Failure to do so may
cause serious personal injury or property damage.
