2-10 must be running at medium speed without load. Increase the speed and load gradually with the
accumulation of breaking-in mileage.
b. Because the brake plat is not broken in on a new vehicle,in order to ensure safety and reduce wear,avoid
harsh brake, and brake for multiple times to break in the brake plate faster.
c. It is better to avoid driving vehicle on steep roads or in bad conditions during breaking-in period.
d. Pay special attention to engine coolant temperature meter and oil pressure meter.Check engine oil level
frequently and make sure engine works in normal temperature and good lubrication.
e. Maintain the vehicle strictly according to first-time maintenance requirements to bring the vehicle into
normal usage life under good condition.
7.vehicle towing
There are towing facilities both in the front and rear end of MK-1 sedan for towing other vehicles and being towed.
To ensure safety, pay attention to the following instructions when towing.
(1) Towing car Towing car should be started and shifted steadily.The speed should be no more than 40km/h.
(2) Follow the instructions below when being towed:
a. Steering system of the vehicle being towed works well.
b. Braking system of the vehicle being towed works well or it cannot be towed with a rope and must be
towed with the towing shaft instead.
c. Release park brake and shift the transmission to neutral gear when the vehicle is being towed.
d. Turn the ignition switch to ACC to allow turning signal lights,braking indicator to be turned on when
necessary.
e. The towing rope must be tensioned in the towing process.
f. If the purpose of towing is to start the engine, shift the transmission to the 2nd or 3rd gear to increase
engine speed. It is good for starting the engine.
8. Instructions to save fuel when using the vehicle
(1) Reasonable load Do not store useless articles in luggage compartment because they consumes fuel for
nothing.
(2) Correct driving style Instructions as follows:
a. When engine is started, do not heat it but press the accelerator pedal slightly, drive the vehicle slowly
and accelerate gradually.
b. Shift to higher gears when driving to allow the engine to work at appropriate engine speed and avoid
running the engine at low or high speed. The engine speed should be higher than 2500r/min when
driving, and higher than 3000r/min when up-shifting.
c. Keep the vehicle speed stable, and avoid harsh acceleration and frequent braking.
d. Pay attention to vehicle speed. Drive at high speed results in excessive fuel consumption.
(3) Organize vehicle usage well Pay attention to the following two instructions.
a. Organize vehicle usage time and avoid short trips. Because at the beginning when the vehicle is started
(around 1km), the engine has not reached its efficiency point, and the fuel consumption doubles
compared to regular.
b. Select a good driving route, avoid driving through the city or blocks with heavy traffic.
(4) Keep the vehicle under good work condition Strictly follow instructions to maintain the vehicle to make
sure the vehicle is under good technical working condition, and inspect and replace key parts that affect vehicle
fuel consumptions. For example:Usage and Maintenance of MK Series - Usage of MK Series
Section 3 Valve Clearance AdjustmentAdjust the throttle gap (see Figure 2-9).
Calculate the thickness of new washer to allow the
gap of the exhaust valve to reach a specified value.
N=T+(A-0.2mm)
Note: where,
N -- Thickness of new washer
T -- Thickness of the washer removed
A -- Measured throttle gap
Calculation formula of the suction valve is: N= T+(A-0.3mm).
(1) Remove the adjusting washer.
a. Rotate the crankshaft until the top of the cam is upwards.
b. The nick of the valve tappet faces toward the front.
c. Press the valve tappet down with a special tool, and place
the tool between the camshaft and the valve tappet (see
Figure 2-10).
Tip:
Place one end, with a mark "9", of the special tool to the position
shown in Figure 1-24 a bit aslant.
If the special tool (B) is put into a deep position too much, it will
be clipped by the washer. In order to avoid the special tool (B) being
too hard to take out, put it into slowly by decreasing the inclination
angle from the suction side.
It is difficult for the special tool (B) to insert due to the shape
of the cam when inserting it from the suction side to the back side of
No.3 cylinder (see Figure 2-10). When adjusting the washer, therefore,
it is advisable to insert from the exhaust side.
d. Press the valve tappet down alternately with the special tool
(A) and (B) to check the throttle gap.
(2) Re-mount the adjusting washer.
a. Mount a new adjusting washer on the valve tappet.
b. Press the valve tappet down with the special tool (A), and
remove the special tool (B).
c. Re-check the throttle gap.Figure 2-9
