Semi-trailer-te maintenance cycle chu mileage leh time-ah a innghat tur a ni. Thurawn bikte chu hetiang hi a ni ("Commercial Vehicle Maintenance atana Technical Specifications" GB/T 18344-2016 en rawh):
1. Nitin Inspection: Trip apiangin tire pressure (standard value: hmalam ke tan 7.5-8.5 bar, hnunglam ke tan 6.5-7.5 bar), lighting system leh brake line-ah leak a awm leh awm loh enfiah thin ang che.
2. Minor Maintenance (30,000 km/thla 6): Engine oil (CI-4 grade 15W-40 diesel oil rawt), oil filter thlak la, suspension bolt torque (standard value: U-bolt te chu 400-500 N·m a tling tur a ni) enfiah rawh.
3. Major Maintenance (100,000 km/1 year): Maintenance thil tenau bakah hian air filter leh fuel filter thlak la, wheel hub bearing clearance enfiah bawk ang che (axial play chu 0.1 mm aia tlem lo tur a ni).
Operating condition bik (hun rei tak-term heavy load emaw tlanga khalh emaw ang chi) ah chuan brake cycle interval 20%-30% tihtlem a ngai a ni. Entirnan, lirthei brake hmang fo thinte chuan kilometer 20,000 danah brake pad thickness enfiah a ngai thin (pad thickness thar 25mm aia tam emaw, a tlukpui emaw, limit>=5mm).
II. Core Maintenance Points leh Operating Specifications te chu a hnuaia mi ang hian a ni

- Tyre chu kilometer 5,000 danah rotate (cross rotation recommended) a, a chhe lo tur a awm loh nan;
- Tread thuk zawng 1.6mm hnuai lam a tlak chuan tire thlak leh (GB 9744-2015-a tarlan danin);
- Tyre pressure monitoring system (TPMS) hman hian tyre puak darh theihna chu 30% aia tam a tihziaawm thei a ni (data source: US NHTSA report).
(II) Braking hman dan tur
1. Air System enkawl dan tur:
- Freezing avanga valve body a chhe loh nan air reservoir tui chu kar tin chhuah tir thin ang che;
- Thla 6 danah desiccant thlak leh thin ang che (adsorption desiccant a chhiat chuan braking a tikhawtlai thei).
2. Mechanical Component hrang hrang: 1.1.
- Brake drum wear limit chu 2mm (vernier caliper hmanga teh) a ni. He limit pelh hian turning emaw replacement emaw a ngai a ni.
- Brake chamber push rod stroke 40mm (standard value: 20-30mm) aia tam a nih chuan clearance chu siamrem rawh.
(III) Suspension leh Frame te
- Thla tin leaf springs-ah a crack awm leh awm loh enfiah thin ang che (leave hmasa leh pahnihna lam ngaihtuah thin ang che).
- Saddle pin-te chu thla thum danah lubricate thin ang che (NLGI Grade 2 lithium grease hmangin).
- Frame weld-a crack awmte chu siamthat nghal tur a ni (crack sei zawng 5mm aia tam a nih chuan lirthei khalh khap a ni).
