2. BEFORE DRIVING YOUR JAC
BREAKING IN YOUR VEHICLE
Operate the vehicle at moderate speeds during the first 1,000 km (600 miles) to break it in. Make certain that the follow鄄
ing points in particular are strictly observed.
荫
Allow the engine to warm up fully until the coolant temperature reaches about 60益(140℉).
荫
Avoid racing the engine, abrupt start, acceleration and braking.
荫
Avoid overloading the vehicle, as this will result in a shorter life.
荫
Avoid high speed operation as far as possible. During break-in operation, make sure that the engine speed does not
exceed 1,500 rpm.
Make sure that your vehicle does not miss the first 1,000 km(600 miles) and 5,000 km (2,500 miles ) inspections.
After the first 1,000 km (600 miles) and 5,000 km(2,500 miles) or driving, take your vehicle to your nearest service shop
for inspections based on the 'Maintenance Requirements'.
NOTE: Must have the engine of your vehicle checked at the authorized JAC service station. If you do not follow the pre鄄
caution it may cause a series damage to the engine and is not covered by JAC.
1. IMPORTANT INFORMATION
The followings are very important for the correct management and economic use of JAC vehicles, and they shall be read
carefully before use and maintenance.
Nameplate
The nameplate is located near the VIN, on which it marked with information
about the vehicle, such as its vehicle model, engine model, ex -works date,
etc.
Chassis number
The chassis number, that is VIN code number, is stamped on the outer side of
the right longeron end of the frame.
Overload
Overloading will shorten vehicle's service life, but also bring about potential
risk to safe driving.
The loading mass must be limited to the specified range of the max. total mass
for vehicle, and the load distributions on the front and rear shafts shall not be
more than the carrying capacity of the vehicle shafts. Please refer to the techni鄄
cal specification sheet for the rated total mass value and shaft loading capacity.
