Tilmaamaha iyo xuduudaha suunka kontoroolka PU ee mashiinka cajiinka waa in la doortaa iyadoo lagu darayo habka wax soo saarka, shuruudaha qalabka iyo astaamaha cajiinka, soo socda waa hordhac faahfaahsan oo ku saabsan qeexitaannada guud iyo xuduudaha muhiimka ah:

Qeexitaannada guud

Dhumucda
Dhumucda caadiga ah: 0.8mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm.
Shuruudo gaar ah: waxaa loo habeyn karaa qeexitaanno dhumuc weyn ama khafiif ah (sida 0.5mm-5mm)

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

Midab
Midabada caadiga ah: caddaan, buluug, cagaar, cagaar madow, madow
Codsiga cad: shuruudaha heerka cuntada, oo ku habboon in si toos ah loola xiriiro xaaladda cajiinka
Codsiga buluug/cagaaran: si fudud loo kala saari karo khadadka wax soo saarka kala duwan ama meelaha shaqada

Dhammaadka Dusha sare
Dusha sare ee dhalaalaysa: ku habboon gaarsiinta cajiinka guud
Dusha sare ee matte: waxay yareysaa milicsiga, oo ku habboon nidaamyada kormeerka muuqaalka
Dusha sare ee qaabaysan: tusaale ahaan qaabka dheemanka, qaabka lafaha si loo kordhiyo is jiidjiidka loona ilaaliyo in cajiinka simbiriirixan.
Naqshad daloolsan: hawo wanaagsan oo u gudubta, oo ku habboon cajiinka u baahan in la hawo geliyo (tusaale ahaan baastada).

Ka-hortagga Usha oo xooggan
Dusha siman/naqshad qaabaysan:Waxay yareysaa dhegganaanta cajiinka, si siman u gudbinta, looma baahna joogsiyo joogto ah oo lagu nadiifiyo.
Isku-darka hoose ee is-jiidjiidka:Waxay yareysaa isticmaalka tamarta iyo shaqada oo si habsami leh u socota.

Habaynta taageerada
Habayn qeexitaanno badan leh:Dhumucda, ballaca, qaabka iyo midabka waxaa loo habeyn karaa si ay si fiican ugu habboonaadaan moodooyinka mashiinka cajiinka kala duwan.
Tilmaamo gaar ah:baffles ikhtiyaari ah, goonno, hagayaal, iwm. si looga hortago in cajiinka uu daato ama uu wareego.
