Tilmaamaha iyo cabbirada suunka gudbinta PU ee mashiinka cajiinka ayaa loo baahan yahay in lagu xusho iyadoo lagu darayo habka wax soo saarka, shuruudaha qalabka iyo sifooyinka cajiinka, kuwan soo socda ayaa ah hordhac faahfaahsan oo tilmaamayaasha caadiga ah iyo xuduudaha muhiimka ah:

Tilmaamaha guud

Dhumucda
Dhumucda guud: 0.8mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm.
Shuruudaha gaarka ah: waxaa lagu hagaajin karaa qadhaadh ama qafiifsan tilmaamo (sida 0.5mm-5mm)

Ballaca
Balaadhka caadiga ah: 300mm, 400mm, 500mm, 600mm, 800mm, 1000mm
Kala duwanaansho gaar ah: waxaa lagu habeyn karaa iyadoo loo eegayo cabbirka mashiinka cajiinka (tusaale 200mm-2000mm)

Midabka
Midabada caadiga ah: caddaan, buluug, cagaar, cagaar madow, madow
Codsiga cad: shuruudda heerka cuntada, ku habboon in si toos ah loola xiriiro dhacdada cajiinka
Codsiga buluug/cagaaran: fududahay in la kala saaro khadadka wax soo saarka ee kala duwan ama meelaha shaqada

Dusha sare ayaa dhammaatay
Dusha dhalaalaya: ku habboon gudbinta cajiinka guud
Dusha sare ee matte: waxay yaraynaysaa milicsiga, ku haboon hababka kormeerka aragga
Dusha qaabaysan: tusaale ahaan qaabka dheemanka, qaabka herringlane si loo kordhiyo is jiid jiid loogana ilaaliyo in cajiinka uu simbiriiro.
Naqshad dalool leh: hawo wanaagsan oo daloolin, oo ku habboon cajiinka u baahan in la neefsado (tusaale baastada).

Usha ka-hortagga xooggan
Naqshadaynta oogada siman/qaabaysan:waxay yaraynaysaa ku dhegga cajiinka, gudbinta siman, looma baahna joogsi joogta ah oo nadiifin ah.
Isku-dhafka hoose ee is-jiidhka:Waxay yaraynaysaa isticmaalka tamarta waxayna yaraynaysaa hawlgalka.

Taageerida habaynta
Waxka beddelka-qeexidda badan:Dhumucda, ballaca, qaabka iyo midabka ayaa loo habeyn karaa si ay si fiican ugu dhigmaan moodooyinka mashiinka cajiinka ee kala duwan.
Tilmaamo gaar ah:khariidado ikhtiyaari ah, goonooyin, hagayaal, iwm. si looga hortago in cajiinka uu daadanayo ama beddelo.
