PROCEDURE:
●Remove the cylinder
Remove the lock washer(1)Use the special four-jaw sleeve or hook wrench to remove the upper
adjustment nut (2).
Remove the rubber pad(3).
Hold the lower connection board assembly(7) in one hand,and loosen the adjustable nuts(2) with the
special four-jaw sleeve or hook wrench in the other hand.
Remove the upper dust cover(4) .
Remove the lower connection board assembly(7) .
Remove the shaft ring (5) and the connecting steel ball (6) on the upper part of the front riser.
Remove the lower connection board assembly(7).
Remove the connecting steel ball on the lower connection board assembly(7).
●Installation:
When reassembling, the joint steel balls should be evenly coated with grease, pay attention to the amount
of grease.
The adjusting nut close to the upper dust cover (4) requires a torque of about 14 N.m, so that it can be
flexibly rotated without jamming.
The upper adjustment nut only needs to be screwed to the bottom nut groove, and should not be too tight
to prevent the rubber pad (3) from being deformed too much.
CAUTION：
●It needs to remove the head assembly,handlebar assembly and front shock absorber at first.
●
Pay attention to fixing the vehicle to be repaired during the disassembly process to prevent accidents caused by
dumping.
●
Check whetreher there are some abnormal phenomena such as partial grinding and rust on the connecting steel
ball. If there are, please go to Shengshi official website to buy regular accessories. If not, be sure to clean the old
grease and then smear.Must check the joint ball for missing when reassembling.
●It is reasonable to adjust the steering tightness. If it is too loose, it will cause slight shaking and abnormal noise
when the front of the vehicle is in emergency braking. If it is too tight, the rotation will be inflexible, resulting in
safety hazards.
●
If you have the ability and have the right tools, you can replace the shaft collar (5) and the lower dust cover (8)
at the lower joint assembly. Pay attention to the protection of the lower plate during the replacement process;
after replacement, be sure to check the parallelism between the column and the shock absorbing hole, and the
verticality of the column and the lower plate.
●When the front fork has a slight sway or the steering wheel swings while braking.
First check whether the front tire pressure is the recommended air pressure at normal temperature: normal
temperature: standard 250kPa.
●If it is lower than the recommended air pressure, first inflate the front tire air pressure to 350kPa, and then
deflate to the test drive to check whether it is released. If the front wheel is otherwise lifted and turned to check
the tread, if it is eccentric or deformed, the front tire needs to be replaced. If you need to re-adjust the adjustment
nut.

PROCEDURE:
●Check the seat ring
Check whether there is worn on seat ring(2),and If there is,please purchase and replace it on Shengshi
official website.Press the seat in place with a suitable tool and apply grease.
●Replace the oil filter.
Place the oil plate underneath and remove the oil-cooled joint(5), O-ring (4), and oil filter(3) with
appropriate tools. When replacing the oil filter (3), the O-ring (4) must be replaced at the same time.
Always tighten the oil-cooled fitting (5) to the standard torque value during reassembly.
●Let out the oil in the frame tube
Place the oil plate underneath and remove the oil drain bolt(7) and seal(6) with a suitable tool,exhust the
oil from the frame tube. Refer to the instructions for detailed steps to replace the oil. It is recommended to
replace the oil drain bolt(7) and the seal(6) at each time to change the oil to prevent oil leakage.
●Side bracket
Use a Phillips screwdriver to remove the side bracket spring(12) to prevent personal injury when the
spring is retracted; remove the nut(8) and bolt (11) with a suitable tool; remove the side bracket(10) and
bushing(9). When reassembling, the bushing(9) is first greased and placed in the frame (1).The side
bracket a is a low seat version and b is a high seat version.
CAUTION：
●Remove first the wind deflector COMPONENT, handle bar COMPONENT, steering column COMPONENT.
●The seat ring should be greased to reduce the resistance of the front fork.
●The wasted engine oil should be recycled and handed over to a qualified institution for disposal.It is forbidden
to dump and pollute environment or water source.
●Be careful when disassembling the side bracket springs. All parts should be properly assembled in place.
●
Side stand "a" Type :Side stand "a" Type :the bottom edge has a jagged shape and number "7" is matched with
the ZT310-X front shock absorber;Side stand "b" Type :matching ZT310-T (40) front shock absorber use. The
letters behind the ZT+4 number on the inside of the bottom cylinder represent the shock-absorber models, such as
“X”, “T40”. For example, ZT1908T40: "ZT" stands for ZONTES, "1908" stands for August 2019, and "T40" is
the shock absorber model. Different models have different shock absorber lengths, so be careful to distinguish
them clearly.

PROCEDURE:
●Air filter element
If you need to maintain the air filter element, first remove the cushion, right side cover and so on. Remove two
standard parts①on the air filter with the tool, remove the box cover②
and then pull off the air filter element. Use
a blow gun to blow from the dusty side of the filter element and blow off the dust on the surface of the filter
element. If the blow is reversed, the dust cannot be cleaned, which may cause engine damage or increased intake
resistance, which may affect the driving experience. If there is any damage, please log in to Shengshi official
website to purchase additional parts after sale. Make sure the assembly is in place during assembly.
●Oil accumulation pipe and water supply pipe
When flushing the motorcycle, avoid water entering the inside of the air filter; a small amount of water can be
removed and the accumulated oil pipe (3) and water pipe (4) can be removed. Make sure that there is no water
inside to start the engine. The oil storage pipe should be inspected regularly. If the accumulated oil is more, it
should be released in time.
CAUTION:
●Regularly check whether the filter element of the carbon tank and air filter is not ventilated, otherwise it may
cause the oil supply to affect the driving experience.
●When blowing dust, pay attention to maintain a certain distance to avoid excessive damage to the filter
element.
